Brandur 4da4bd3ff3 Colocate uname helpers + tests
Colocates the helper methods for looking up a uname by renaming them to
have the same prefix as the base method (i.e. `get_uname`).

Also adds an additional rescue in case we try to run an executable on a
system but it wasn't founded (this should never happen).

Also adds some tests to make sure that each method gets at least a very
basic amount of exercise in the test suite.
