Subject: selftests: vm: pkeys: fix powerpc access right definitions
For powerpc, PKEY_DISABLE_WRITE and PKEY_DISABLE_ACCESS are redefined only
if the system headers already define them. Otherwise, the test fails to
compile due to their absence. This makes sure that they are always
defined irrespective of them being present in the system headers.
