perf test: Add mechanism for skipping attr tests on kernel versions
The first two version numbers are used since that is where the ABI
changes happen, so seems to be the most useful for now.
'Until' is exclusive and 'since' is inclusive so that the same version
number can be used to mark a point where the change comes into effect.
This allows keeping the tests in a state where new tests will also pass
on older kernels if the existence of a new feature isn't explicitly
broadcast by the kernel. For example extended user regs are currently
discovered by trial and error calls to perf_event_open.
