fix gpm command line

The gpm runscript quotes some computed command line options when it shouldn't, meaning they get parsed as a single argv entry, producing a confusing error message, failing and constantly attempting to restart.

Logs below are with logging hacked in, they don't actually feature in the runscript before or after:

Unfortunately the daemon conflates "not daemonizing" with "showing all your debug". It would be nice to patch gpm to separate the two modes. This could also improve the systemd unit file which currently deploys a forking service (with a sleep!) which might make such a patch more appealing.
