selftests/x86/test_vsyscall: Improve the process_vm_readv() test
The existing code accepted process_vm_readv() success or failure as long
as it didn't return garbage. This is too weak: if the vsyscall page is
readable, then process_vm_readv() should succeed and, if the page is not
readable, then it should fail.
