[PATCH 4/6] fsmonitor: Make output of test-dump-fsmonitor more concise

[Alex Vandiver <alexmv@dropbox.com>]

Rather than display one very long line, summarize the contents of that
line.  The tests do not currently rely on any content except the first
line ("no fsmonitor" / "fsmonitor last update").
