Philip Withnall 26c433d26c tests: Speed up the file test and make it more reliable
Sometimes this test was timing out due to the file monitor notifications
taking longer than the arbitrary 2s delay before ending the test and
checking its results at the end of `iclosed_cb()`.

Avoid that timing-dependence by ending the test when the expected file
monitor notifications are seen, or after a 10s timeout (if so, the test
is failed).

This makes the test run 4× faster in the normal case, as it’s no longer
waiting for a timeout to elapse if the file monitor notifications come
in sooner.
