test: skip some console tests on dumb terminal

Add capabilities to common test module to detect and skip tests
on dumb terminals.

In some of our build environments, like s390x, the terminal
is a dumb terminal meaning it has very rudimentary capabilities.
These in turn prevent some of the tests from completing with errors
as below.
