Reenable test_posix.test_fs_holes()

Since 2012, when the test was skipped from Python 3.3.0b1 (commit
3b4dd24c42), Linux now have a good
support for punching holes in filesystems.

Only 00160-disable-test_fs_holes-in-rpm-build.patch and
00163-disable-parts-of-test_socket-in-rpm-build.patch patches used
@unittest._skipInRpmBuild @unittest._expectedFailureInRpmBuild
decorators, but these 2 patches have been removed: remove
00132-add-rpmbuild-hooks-to-unittest.patch and
WITHIN_PYTHON_RPM_BUILD environment variable as well.
