sysusers,tmpfiles: make standalone versions full-featured

This effectively reverts 3537577c37. Originally,
the #ifdefs were added because we didn't want to pull in the whole tree of
libmount and other dependencies in standalone versions. But dependencies are
now loaded through dlopen(), so this is not needed anymore. (And doesn't even
make much of a difference.)
