selftests/mm: Define PKEY_UNRESTRICTED for pkey_sighandler_tests
Commit 6e182dc9f268 ("selftests/mm: Use generic pkey register
manipulation") makes use of PKEY_UNRESTRICTED in
pkey_sighandler_tests. The macro has been proposed for addition to
uapi headers [1], but the patch hasn't landed yet.
Define PKEY_UNRESTRICTED in pkey-helpers.h for the time being to fix
the build.
