[PATCH] testsuite: fix cap_userns for kernels >= v5.12

[Paul Moore <paul@xxxxxxxxxxxxxx>]

Starting with Linux v5.12 CAP_SETFCAP is required to map UID 0/root.
This is due to kernel commit db2e718a4798 ("capabilities: require
CAP_SETFCAP to map uid 0").  In order to resolve this in the test
suite allow the test_cap_userns_t domain to exercise the setfcap
capability.
