From: Geliang Tang <tanggeliang@kylinos.cn>

Just like handling ENOTSUPP in test_lsm_cgroup_functional(), this patch
adds a new helper test_progs_get_error() to check whether the input error
is ENOTSUPP (524) or ENOTSUP (95). If it is, invoke test__skip() to skip
the test instead of using test__fail().

Use this helper in ASSERT_OK() before invoking CHECK() macro.
