getdeps: fixup testpilot new test recording

Summary:
In the Facebook infrastructure the testpilot runner talks
to a service to determine whether a given test should be run locally.

The remote service was returning an error for some tests because they
didn't have enough configuration specified.

This diff associates some configuration with the tests based on the
host type and makes things happier.
