Bump up timeouts for DSVM and probe test jobs

DSVM recently got a bunch more middlewares enabled, so it's running more
tests than it used to.

I can't think of much that's changed for probe tests, but I feel like
I've seen it popping timeouts more often lately.

Note that the new timeouts are still lower than the typical run-time of
our longest-running jobs (currently grenade / tempest-ipv6-only).
