nixosTests/cosmic: skip testing GUI app if not present

Browse source 
In cases when a given GUI app is absent (encountered when excluding
packages like `cosmic-term`, etc), the test fails because the GUI app
doesn't launch. That, while being a failure, is not connected to the
COSMIC DE itself. So if a binary is missing, skip launch-testing it.
