test-runner: add ofono/phonesim to test-runner

A new option 'sim_keys' can be put in the SETUP group. If
sim_keys=ofono, then test-runner will attempt to start ofono
and phonesim to be used with EAP-SIM/AKA. If ofono OR phonesim
are not found the test will be skipped.

Any other value of 'sim_keys' should be a 'keys' file
e.g. /tmp/sim_keys.conf which should contain hardcoded
SIM/AKA key values.
