llvmbot monitor: Print generated time only once, at top of page
Previously we printed this for all the sections but the time
is the time we generated the HTML not the time we polled the API,
so it didn't need to be per category.
It's at the top so you can tell at a glance if there's an issue
with the script that means it can't update the page.
It's a bit awkward to place it because it needs to go in a table
with content so that it aligns nicely. This leads to a "bug" where
if you had nothing to print, you'd see no "Generated" line, but I
am ok with that.
If the status monitor was blank, I'd have bigger problems than
what time it was made.
