[tools] winetest/cron: Refresh the pattern page regularly.

[Francois Gouget]

This ensures the links to the WineHQ bugs contain a mostly up-to-date
status and bug description even after the day's WineTest jobs have
completed.

Feel free to adjust pattern_interval to taste. I figure 10 minutes
would be a minimum and 4 hours would be really long. So I picked one
hour to be sure to put a negligible load on Bugzilla, but that may be
too conservative.
