selftests/resctrl: Skip L3_CAT when no exclusive cache portion exists
L3_CAT requires an exclusive cache portion to test cache allocation.
This means that the cache portion used by the test can't overlap with
cache portions into which other agents may allocate.
Some platforms legitimately report every cache portion as shareable,
leaving no exclusive cache portion for the test and causing L3_CAT to
fail.
Skip the L3_CAT when the platform has no exclusive cache portion that
the test can use.
