context: Include a command line argument to run all except certain tests

A new command line argument (-R, which is the oposite of current -r) that allows
to run all test cases except the ones indicated through the command line.

Some command line examples:

* Run all except the distro test case:
$ oe-selftest -R distrodata

* Run all except the archiver test case and a single bblayers unit test
$ oe-selftest -R archiver bblayers.BitbakeLayers.test_bitbakelayers_add_remove
