Kim Phillips 98c6c8a1d0 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.
