phosphor-gpio-monitor: ignore extra args

The phosphor-gpio-monitor@.service template has an EXTRA_ARGS which
in some configs can be empty.  systemd will end up launching the
process with an extra, empty argument.  CLI11 fails on this unless
we give an explicit `allow_extra` call.

Observed in hardware testing:
```

Aug 09 19:28:46 witherspoon-Y230UF71K03T phosphor-gpio-monitor[632]: Run with --help for more information.
