build-system/pyproject: Handle wheel not found exception.

The current error is very uninformative, use a proper exception to
give more information when this happens:
`In procedure map: Wrong type argument: #f`

After this patch:
`In procedure raise-exception:
ERROR:
  1. &no-wheels-found`

* guix/build/pyproject-build-system.scm (&no-wheels-found): Add exception.
(install): Handle exception.

build-system/pyproject: Avoid PEP427 substitution on binary files.

In some rare cases, the dest-path can be an elf-file, which are
unreadable by substitute*, leading to an error instead of just
continuing which makes more sense in this case.

* guix/build-system/pyproject.scm (check): Guard substitution attempt
with basic readability guarantees.

build-system/pyproject: Use copy-recursively instead of merge-dirs.

Using rename-file, the destination had to be empty otherwise it would error
out.  This has been fixed by the use of copy-recursively, really merging them.
Changing this makes merge-directories mostly a duplicate of
copy-recursively, thus fully switch to copy-recursively.

* guix/build/pyproject-build-system.scm (install)
<python-hashbang>: Remove it, used only once.
<merge-directories>: Remove it, replace its calls by copy-recursively
and delete-file-recursively.

build-system/pyproject: Add python test-backend.

* guix/build/pyproject-build-system(check): Add python test-backend.

This will help in cases where a simple `python -m module args` call has
to be made instead of fully replacing the 'check phase, e.g. unittest
or django. This is never enabled unless #:test-backend 'python is set,
so it doesn't break anything.

As an example, the following snippet...

(arguments
  (list #:phases #~(modify-phases %standard-phases
                     (replace 'check
                       (lambda* (#:key tests? #:allow-other-keys)
                         (when tests?
                           (invoke "python" "-m" "unittest"
                                   "diff_match_patch.tests")))))))

...can be transformed like this:

(arguments
  '(#:test-backend 'python
    #:test-flags (list "-m" "unittest" "diff_match_patch.tests")))

build/pyproject: Really merge directories in install phase.

Using rename-file, the destination had to be empty otherwise it would
error out.  By using copy-recursively, a directory can be copied onto a
pre-existing directory, really merging them.  This problem manifested
itself attempting to build the python-pyre package.

Solving #596.

* guix/build/pyproject-build-system.scm (install)
<merge-directories>: Use copy-recursively instead of rename-file.
