DEFAULT_REPO was the absolute /root/troupe-standup, so a copy's
`--selftest` -- the invocation selftest_sweep.py uses, no --repo, cwd =
the tree under sweep -- graded the home checkout and reported the copy
clean. Derived from __file__ instead: the default is the checkout the
tool lives in. Measured on a clone at c3058d5 with drifted docs: before,
repo-less --selftest 20/20 rc 0 vs --repo . 19/20 rc 1; after, 19/20
rc 1 both ways.
Also in this commit:
- verify.run_leg: one elapsed-ms clock (_elapsed_ms) and one except arm
for TimeoutExpired/OSError, instead of three copies of the arithmetic;
- write_probe c13: roster read from FLAG_PROBES rather than a hardcoded
three, and selftest_sweep.py --write-baseline added to the table;
- docs/TOOLS.md: the selftest_sweep row grows the flags it now prints.
