Intel-SIG: commit 20df7375 selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM test.

--------------------------------

Update the arch_prctl test to check the permission bitmap whether the
requested feature is added as expected or not.

Every non-dynamic feature that is enabled is permitted already for use.
TILECFG is not dynamic feature. Ensure the bit is always on from
ARCH_GET_XCOMP_PERM.
