Specified user in daemon config is not respected.

[bartoszwalicki]

Daemon user options passed in file /etc/default/triggerhappy are not respected due to hardcoded nobody user in triggerhappy.service service config file.

This is probably better fixed by adding EnvironmentFile=/etc/default/triggerhappy, and then a $DAEMON_OPTS suffix to the ExecStart= line.

Alternatively (because this is systemd), it would probably just be better to set User= (but that breaks opening input files at startup).
