configure.ac: autodetect availability of systemd
Import systemd's official suggestion [1] how this should be handled in packages
using autoconf. A side effect of this is the removal of the hardcoded fallback
path "/lib/systemd/system" which leaks build host information when cross
compiling v4l-utils and therefore defeats reproducible builds.
