After this commit, when both modules are imported:

- if pyproject is imported before, the warning is 'pypi-uri' is
deprecated, use '(@ (guix build-system pyproject) pypi-uri)' instead

- if python is imported before, the warning is `pypi-uri' imported from
both (guix build-system python) and (guix build-system pyproject)

This seems convenient enough to warn for deprecation in the short term,
while avoiding any breaking changes.

* guix/build-system/pyproject.scm (pypi-uri): Move the procedure from
(guix build-system python) here.

* guix/build-system/python (pypi-uri): Drop definition, import it
from (guix build-system pyproject) and deprecate it.

* gnu/packages/openldap.scm: Reorder modules to get the right warning.

* gnu/packages/pypy.scm: Likewise.

* gnu/packages/*.scm : Drop module (guix build-system python).

* tests/import/pypi.scm: Likewise.

Until now users would have to cargo cult or inspect the private
%default-modules variable of (guix build-systems gnu) to discover which
modules to include when extending the used modules via the #:modules argument.

The renaming was automated via the command:

  $ git grep -l %gnu-build-system-modules
    | xargs sed 's/%gnu-build-system-modules/%default-gnu-imported-modules/' -i

* guix/build-system/gnu.scm (%gnu-build-system-modules): Rename to...
(%default-gnu-imported-modules): ... this.
(%default-modules): Rename to...
(%default-gnu-modules): ... this.  Export.
(dist-package, gnu-build, gnu-cross-build): Adjust accordingly.
