Bug Description

Like bug 1812352

In the ubuntu_kernel_selftests, the skipped test will uses return code 4 (KSFT_SKIP).

However the code to handle this non-zero return code was not implemented in the kselftest framework. And this will generate some false-positives results as those skipped tests were treated as a failure.

In X-KVM kernel, test_user_copy.sh test in user will fail because of this:
    user: module test_user_copy is not found [SKIP]
    not ok 1..1 selftests: test_user_copy.sh [FAIL]
