There are so many "ENOTSUPP" (-524) errors when running BPF selftests
on a Loongarch platform since lacking BPF trampoline on Loongarch:

This patch uses ASSERT_OK() instead of CHECK() to skip these "ENOTSUPP"
errors. With this change, the new output of these selftests look like:

'''
 #77/1    d_path/basic:SKIP
 #77/2    d_path/check_rdonly_mem:OK
 #77/3    d_path/check_alloc_mem:OK
 #77      d_path:OK (SKIP: 1/3)

 #167     module_attach:SKIP

 #277/1   ringbuf/ringbuf:SKIP
 #277/2   ringbuf/ringbuf_n:SKIP
 #277/3   ringbuf/ringbuf_map_key:SKIP
 #277     ringbuf:SKIP
 ... ...
 #382     test_bprm_opts:SKIP
 ... ...
 #384     test_ima:SKIP
 ... ...
 #397     trace_ext:SKIP
