"gdb.arch/i386-pkru.exp: probe PKRU support" shouldn't FAIL if not supported

Currently I get:

 (gdb) print have_pkru()
 $1 = 0
 (gdb) FAIL: gdb.arch/i386-pkru.exp: probe PKRU support
 UNSUPPORTED: gdb.arch/i386-pkru.exp: processor does not support protection key feature.

Probing suceeded, so that should be a PASS -> UNSUPPORTED.

gdb/testsuite/ChangeLog:
2017-03-08  Pedro Alves  <palves@redhat.com>

	* gdb.arch/i386-pkru.exp (probe PKRU support): Handle detecting
	PKRU as not supported as a PASS.
