samba/samba-4.2.2-lib-util-fix-detection-of-systemd-libraries.patch
Alexander Bokovoy 082c9d6058 Fix build with systemd libraries 
systemd-related fixes did not land in Samba 4.2.1 release, they
are in v4-2-test branch _past_ 4.2.1 release.

We need to keep going with a local patch until 4.2.2 release.

Subject: [PATCH 1/2] build: Move systemd checks to lib/util
Only lib/util uses the systemd library, so it makes sense to have the
checks there. This also removes the need for the ctdb build script to
specify an empty tag for the systemd library.
