Support skipped tests

Knowing whether a test failed to run as its prerequisites were not
available, or whether those prerequisites were available and produced
unexpected/incorrect results, is a useful differentiation.

Add support for skipped tests by testing for exit code 77, used through
autotools/piglit/etc to denote a test which detected this and decided to
skip.
