A bunch of tests are currently taking ~60 seconds, dangerously close to
the current 60 seconds timeout. Add some congesion or just bad luck to
a runner, or some other background-task, and we can very easily be
pushed above that.
Since we're rendering on LLVMpipe rather than HW, this isn't as
unreasonable as it might sound at first. So let's copy a trick from
VirGL's CI playbook, and bump the timeout to 180 seconds, three times
of what we currently use.
That might seem a bit excessive, but it's better to make it *very*
unlikely to cause trouble than a little bit unlikely.
