There are still some "ENOTSUPP" (-524) errors left when running BPF
selftests on a Loongarch platform since ASSERT_GE() are used there to
check the return values, not ASSERT_OK():

Just like in ASSERT_OK(), this patch skips ENOTSUPP (524) and ENOTSUP (95)
in ASSERT_GT() too. With this change, the new output of these selftests
look like:

'''
 #17/1    bpf_cookie/kprobe:OK
