[PATCH] selftests/powerpc: Don't run spectre_v2 test by default

[Russell Currey]

The spectre_v2 selftest has issues that I'm unsure of how to resolve.
It uses context to determine intended behaviour, but that context is
unreliable - as an example, when running as a KVM guest, qemu can
deliberately misreport mitigation status for compatibility purposes.

As a result, the selftest is unreliable as a pass/fail test without
the test runner knowing what they expect its behaviour to be.  I don't
think the selftest is useless so we should keep it around, but we
shouldn't have run_tests run it by default.
