match() looks for the start of the line to match our regex, while search just looks for the regex anywhere in the line. I messed this up when converting our greps in shell to python, which was part of breaking the POWER_GOOD flake detection. Most of our matches worked, but let's consistently use this one so we don't mess this up in the future. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6529>
