selftests/mm: remove the local PKEY_UNRESTRICTED fallback

Browse Source 
pkey-helpers.h defines PKEY_UNRESTRICTED itself when the macro is not
already known, a stopgap from when the generic definition was still under
review.  It has been merged since, commit 6d61527d93 ("mm/pkey: Add
PKEY_UNRESTRICTED macro"), so the guard is never taken and the FIXME can
be honoured.

The definition comes from tools/include/uapi/asm-generic/mman-common.h via
TOOLS_INCLUDES, which commit e076eaca59 ("selftests: break the
dependency upon local header files") added so that the mm selftests build
without "make headers".  It is reached through the <asm-generic/mman.h>
that the system <asm/mman.h> includes.  Building the pkey tests with
KHDR_INCLUDES pointing at an empty directory confirms that; emptying
TOOLS_INCLUDES as well is what makes the macro go missing.

No functional change intended.
