selftests: net: lib: support errexit with busywait

BugLink: https://bugs.launchpad.net/bugs/2073788

commit 41b02ea4c0adfcc6761fbfed42c3ce6b6412d881 upstream.

If errexit is enabled ('set -e'), loopy_wait -- or busywait and others
using it -- will stop after the first failure.

Note that if the returned status of loopy_wait is checked, and even if
errexit is enabled, Bash will not stop at the first error.
