Performance test framework has been broken and measured the version
of Git that happens to be on $PATH, not the specified one to
measure, for a while, which has been corrected.
* ab/perf-installed-fix:
perf-lib.sh: forbid the use of GIT_TEST_INSTALLED
perf tests: add "bindir" prefix to git tree test results
perf-lib.sh: remove GIT_TEST_INSTALLED from perf-lib.sh
perf-lib.sh: make "./run <revisions>" use the correct gits
perf aggregate: remove GIT_TEST_INSTALLED from --codespeed
perf README: correct docs for 3c8f12c96c
