Alan Jeffrey afa2f24b68 servo: Merge #19207 - Add --base option to test-perf (from asajeffrey:test-perf-add-base-url-option); r=edunham
<!-- Please describe your changes on the following line: -->

Add a `--base <URL>` option to test-perf, which is handy for two reasons: a) it reduces randomness in tests by allowing tests to be file URLs, and b) it doesn't require running the test suite as root (the tp5n manifest hardwires tests served from port 80 on localhost).
