tests: lines with largefile .* file://$TESTTMP also match on windows

on windows, largefile paths are written as "file:///C:/temp/...", corresponding
to "file:///$TESTTMP/..." (all three slashes shown).
But on posix systems they are written as "file:///tmp/..." corresponding to
"file://$TESTTMP/..." (only two slashes shown).

Write the glob "file:/*/" to match both versions.

"""Extension to verify locks are obtained in the required places.

This works by wrapping functions that should be surrounded by a lock
and asserting the lock is held. Missing locks are called out with a
traceback printed to stderr.

This currently only checks store locks, not working copy locks.
