ci: Exclude tests that show random failures through GitHub actions.

I ran 80 series of full tests, and the following tests showed failures:

As I do not see those failures when running these stand alone on the
same Ubuntu distribution, I've disabled them.

This patch also adds the 'CHECK_GITHUB_ACTION' macro to skip
tests that won't execute successfully through GitHub actions.
We could not use the -k !keyword option, as it can not be
combined with a range of tests.
