selftests: add ksft_exit_fail_perror()

Browse source

Add a version of ksft_exit_fail_msg() which prints the errno and its
string form with ease. There is no benefit of exit message without
errno. Whenever some error occurs, instead of printing errno manually,
this function would be very helpful. In the next TAP ports or new tests,
this function will be used instead of ksft_exit_fail_msg() as it prints
errno.
