build: properly substitute virtlockd.socket

virtlockd.service could be installed to a configurable root,
but virtlockd.socket was hardcoded to installation into a
distro.

* src/Makefile.am (virtlockd.service, virtlockd.socket): Drop
unused substitutions.
* src/locking/virtlockd.socket.in (ListenStream): Don't hard-code
/var.
