Subject: [PATCH 1/2] nixos/lib: hash triggers after converting them to string
 in systemd-lib

This change is made for two reasons:

1.  If `toString config.restartTriggers` containes `\n`, systemd unit
    file will be ill-formed.
2.  This change can limit length of the trigger, although it doesn't
    matter in most cases.
