Unmask dexter debuginfo tests on Darwin

These tests almost certainly work on Darwin anyway, I just wanted to
keep things in a fixed, working configuration, while pushing Dexter
up.

I've left Windows unsupported as the dexter command line will need further
adjustment to run dbgeng. This can be abstracted through the %dexter
substitution, but is a task for another time.
