systemd: ensure /run/lock exists

This is hf2013.11-087-var-lock. It surprised me to see this isn't fixed
upstream, so we'll definitely have to pursue pushing this, and possibly
compare volatiles vs tmpfiles.d to check for other inconsistencies.

Applies hotfix hf2013.11-089-libpng_1.6.10, but avoids the potential impact of
a package upgrade at this time by patching it instead.
