perf: disable automatic housekeeping
Turn off automatic background maintenance for perf tests by default to avoid interference with performance measurements. Do that by using the new file t/perf/config and using it as the system config file for perf tests. Future tests intended to measure gc performance can override the setting locally or call "git gc" explicitly. This fixes a breakage in p2000 caused by gc automatically emptying the reflog due its fake dates from 2005 being older than 90 days.
