Subject: [PATCH net-next 2/9] selftests: net: add skip all feature to ksft_run()

When there is an entire test suite where each test case depends upon
some feature, e.g., psp, it is easier to state the least common
denominator of dpendencies up front, rather than doing:

cfg.require_psp()

at the start of each test.
