check: make results/check.log match everybody else

check: make results/check.log match everybody else

results/check.log is inconsistent with what goes to stdout and $tmp.summary.  It
passes the ran and failed tests through fmt but not the "Not Run" tests for some
reason, and nobody else passes it through fmt.  So fix this to be the same
output as what goes to stdout and $tmp.summary to make for easier post parsing.
Now we'll get

Ran: <single line with all the tests>
Not run: <single line with all the not run tests>
Failures: <single line with all the failed tests>
