gnu: Remove redundant wrapping from packages using ruby-build-system.

Now that the build system does wrapping automatically, it can be removed from
the packages that do it manually.

* gnu/packages/databases.scm (es-dump-restore)[arguments]: Remove #:phases.
* gnu/packages/ruby.scm (ruby-redcloth)[arguments]: Remove #:phases.
  (ruby-httpclient)[arguments]: Remove 'wrap-bin-httpclient from the modified
  phases.

ruby-build-system: Add a new wrap phase.

Wrap files in bin/ and sbin/ with the location of the gem itself and the
location of any other gems in use (GEM_PATH). This ensures that the bin files
will run with the right environment when executed.

It does however mean that native-inputs will also get wrapped up in any
binaries, which is not good, as it increases the size of the closure, and
risks this code being used at runtime.

* guix/build/ruby-build-system.scm (wrap): New procedure.
  (%standard-phases): Add the wrap phase.

ruby-build-system: Add wrap-ruby-program.

A modified copy of wrap-program from (guix build utils). The wrap-program
procedure doesn't work well for Ruby scripts, as it breaks using the -S flag
with ruby to execute the script, as when -S is passed to ruby, it expects the
script on the PATH to use ruby in the shebang, and not bash.

Therefore, to wrap the program, but keep the shebang as ruby, wrap it with a
ruby script instead.

wrap-ruby-program uses .real/foo rather than .foo-real, as this might be
neater. This procedure also includes a call to Gem.clear_paths to make it
possible to set the GEM_PATH through this method, and for it to take effect.

* gnu/build/ruby-build-system.scm (wrap-ruby-program): New procedure.

guix: build: ruby-build-system: Install to the vendor directory

* guix/build/ruby-build-system.scm (install): Install gems to the vendor
  directory, rather than the GEM_HOME. The vendor directory does not include
  the version of ruby used to install the gem in the path, which makes it
  easier to add it to the GEM_PATH for all versions of ruby to use.
  (gem-home): Remove procedure.
* gnu/packages/ruby.scm (ruby, ruby-2.1)[native-search-paths]: Switch to
  lib/ruby/vendor_ruby.
  (ruby-1.8)[native-search-paths]: Remove native-search-paths.
  (gem-directory): Remove procedure.
  (ruby-ansi, ruby-ae)[arguments]: Remove use of gem-directory.
  (ruby-metaclass, ruby-instantiator, ruby-introspection, ruby-mocha,
  ruby-nokogiri, ruby-minitest-tu-shim, ruby-redcloth)[arguments]: Remove use
  of gem-home.
  (ruby-git, ruby-httpclient)[arguments]: Remove use of GEM_HOME.
* gnu/packages/databases.scm (es-dump-restore)[arguments]: Remove use of
  GEM_HOME.

arb: Update to 2.12.0.

* gnu/packages/algebra.scm (pari-gp): Update to 2.9.4.

doc: Correct documentation of NGINX-LOCATION-CONFIGURATION.

* doc/guix.texi (Web Services): The body of an NGINX-LOCATION-CONFIGURATION
is a list of strings and not a string.

gnu: rct: Re-categorize some inputs.

OpenSSL and zlib are referred to by the built package, so we make them
regular inputs.

This is a followup to commit e8b409741baf3b9de30faa8683722375196dd1e9.

* gnu/packages/cpp.scm (rct)[native-inputs]: Move openssl and zlib to ...
[inputs]: ... new field.

gnu: Add rct.

* gnu/packages/cpp.scm (rct): New variable.

gnu: flashrom: Update to 1.0.
