0.5.7 renames the sdist's top directory from python-gnupg-0.5.7 to
python_gnupg-0.5.7, so set PYPI_SOURCE_NAME to make PKG_BUILD_DIR match
what the tarball extracts to. pypi.mk then derives the same PKG_SOURCE
that the explicit line held, so drop it.
Add 001-relax-setuptools-constraint.patch: 0.5.7 tightens its build
requirement to "setuptools >= 68,<75", which the feed's setuptools
84.0.0 does not satisfy, so the build fails with an unmet
"setuptools<75,>=68" dependency. The cap is precautionary and the
package builds unchanged without it.
