tools: Drop libsystemd as a dependency

There are no more users, and we want to disuade people from introducing new
users just for sd_notify() and friends.  Drop the dependency.

We still want the overall --with{,out}-systemd to gate the generation of the
service/unit/mount/etc files.

Rerun autogen.sh, and mark the dependency as removed in the build containers.

tools: (Actually) drop libsystemd as a dependency

When reinstating some of systemd.m4 between v1 and v2, I reintroduced a little
too much.  While {c,o}xenstored are indeed no longer linked against
libsystemd, ./configure still looks for it.

Drop this too.
