[PATCH 2/2] selftests: pstore: skip the frontends the kernel does not have

[Eva Kurchatova]

The console and pmsg frontends are separate options from the backend:
CONFIG_PSTORE_CONSOLE and CONFIG_PSTORE_PMSG can both be off on a kernel
that registers one. pstore_tests checks for both regardless and fails
where they are absent.

Report them as skips instead.
