[PATCH 2/2] python_hatching: remove empty site-packages workaround

[Ross Burton <ross.burton@arm.com>]

Back in 2023 there were random failures from empty directories in the
python site-packages directory, which at the time was believed to be
specific to hatchling and so worked around in this build class[1]. This
is not the case, but changes to hatchling and upgrades would result in
rebuilds, which expose the issue if the build tree is not cleaned.

Since then fixes have been added to python3[2] and python3-build[3]
which resolve this issue at a lower level, so the workaround in this
class should be no longer needed.

[2] oe-core 73de8daa629 ("python3: backport the full fix for importlib scanning invalid distributions")
    oe-core 855d1111c3d ("python3: prefer valid dists when searching for entry points")
[3] oe-core bd7225f5b84 ("python3-build: verify that found dependencies are valid")
