gnu: texlive-bin: Fix the tlmgr utility.

Previously, it would error out, not finding its Perl modules, and later not
finding config.guess.  This utility is useful to query the local TeX Live
package database (texlive.tlpdb).

(texlive-bin)[inputs]{config}: New input.
[phases]{postint}: Add a symlink to the 'config.guess' script.  Patch the
tlmgr.pl script so that it can find its Perl modules and other resources.

gnu: texlive-bin: Unpack the texlive-scripts and texlive-extra inputs early.

This allows the sources to processed normally by the other phases such as
patch-source-shebangs.

[phases]{unpack-texlive-extra, unpack-texlive-scripts}: New phases.
{postint}: Move the unpacking of the texlive-extra and texlive-scripts inputs
to the above newly added phases.  The installation of these extra directories
now simply uses copy-recursively.

gnu: texlive-bin: Replace python-2 by python.

gnu: Add texlive-wasy.

* gnu/packages/tex.scm (texlive-wasy): New variable.

gnu: texlive-stmaryrd: Actually include the fonts.

* gnu/packages/tex.scm (texlive-stmaryrd): Rewrite package to inherit from a
