perf test shell: Make perf's inet_pton test more portable
Debian based systems such as Ubuntu have dash as their default shell. Even if the normal or root user's shell is bash, certain scripts still call /bin/sh, which points to dash, so we fix this perf test by rewriting it in a more portable way.
