Mitigation patching test iterates over a set of mitigations irrespective
of whether a certain mitigation is supported/available in the kernel.
This causes following messages on a kernel where some mitigations
are unavailable:
Spawned threads enabling/disabling mitigations ...
cat: entry_flush: No such file or directory
cat: uaccess_flush: No such file or directory
Waiting for timeout ...
OK
This patch adds a check for available mitigations in the kernel.
