logind: enforce a limit on inhibitors we hand out

For similar reasons as the recent addition of a limit on sessions.

Note that we don't enforce a limit on inhibitors per-user currently, but
there's an implicit one, since each inhibitor takes up one fd, and fds are
limited via RLIMIT_NOFILE, and the limit on the number of processes per user.
