package/python3: fix config directory pattern

Previously, when running `PYTHON3_REMOVE_USELESS_FILES`, the hook to
clean up files from the python config directory assumed a pattern of
"config-$(VERSION)m-$(PLATFORM_TRIPLET)".

However, the "m" ABI suffix was dropped in python 3.8, so the hook would
never actually find files to delete. No error was raised due to the use
of a subshell to invoke find.

Also, if a platform triplet is not detected during the configure stage,
the config directory (LIBPL) defaults to `config-$VERSION`, and has no
trailing `-$PLATFORM_TRIPLET`.

Now, we glob anything after the version to ensure files get deleted.
