package/pkg-python: invalidate precompiled _sysconfigdata*.pyc

For per-package directories, we fixup the _sysconfigdata*.py files, so
that they get proper path pointing to the current package's direcotry
structure.

However, the corresponding, pre-compiled blobs _sysconfigdata*.pyc were
left around, and thus are inconsistent with their source. They might
also be regenerated when a package would install a python module; this
regeneration would trigger the soon-to-be-introduced overwrite
detection.

This commit simply removes _sysconfigdata*.pyc files; they will anyway
be regenerated by the PYTHON{,3}_CREATE_PYC_FILES target finalize hooks.
This is an efficient way to guarantee the consistency between the source
and precompiled versions, and to not trigger the overwrite detection.
