phosphor-gpio-presence: Add expected method for CLI11

The Phosph-gpio-presence@.service template has a --drivers and
--extra-ifaces which can be empty in some configurations[1].
systemd will end up launching the process with an extra empty
argument. CLI11 will fail unless we give an explicit
"--drivers=<value> or --extra-ifaces=<value>".
Add the expected method to --drivers and --extra-ifaces to limit the
number of incoming parameters for parameters.

Observed in hardware testing:
```
--drivers: 1 required TEXT missing
Run with --help for more information.
```
