Set key_control to false in default config

[Allan LeSage]

Just discussing with cyphermox and Wellark, consider changing the default config to ship with key_control=false , else this service simply exits. This MacBook Pro 5,5 doesn't have a wifi key for the record; a few other examples including Wellark and nuclearbob have found this config change to be necessary.

Assigning to Mathieu for his consideration, please let me know if I can provide more info.

Confirming; this needs a profile created for the hardware, and a minimal fix to not fail hard if no killswitch combo is available.
