fix-configure.patch is removed as it's not appropriate, and the new
version of util-linux has solved the problem this patch is trying to solve.
util-linux-ensure-the-existence-of-directory-for-PAT.patch is removed as
the new version of util-linux has solved the problem this patch is trying
to solve.
util-linux-native.patch is rebased.
util-linux-ng-replace-siginterrupt.patch is rebased.
Add PACKAGECONFIG for 'pylibmount' to build out python bindings for libmount
optionally. util-linux-pylibmount is added to PACKAGES if PACKAGECONFIG has
'pylibmount' in it.
Fix PACAGECONFIG for 'systemd' as the new version has changed things related
to systemd. Now util-linux would have a dependency on systemd if 'systemd' is
in PACKAGECONFIG.
Fix SYSTEMD_PACKAGES, SYSTEMD_SERVICE and SYSTEMD_AUTO_ENABLE variable to match
the new version.
Four lines in do_compile task are deleted because they caused do_compile failure
and nowhere in util-linux are they used. Corresponding files are also removed.
