guado_moblab-paladin has had a number of cases where the moblab_quick suite times out at 2h.  Reduce it to 90 minutes.

All data here is since the beginning of April ~35 days.

Successful builds normally take ~42 minutes:

There's only one successful build over 90 minutes, yet 15 of the failed ones took over 90 minutes (and many/most went 2h before they were aborted).

The "successful" build actually failed ( crbug.com/717336 ).  https://luci-logdog.appspot.com/v/?s=chromeos%2Fbb%2Fchromeos%2Fguado_moblab-paladin%2F5816%2F%2B%2Frecipes%2Fsteps%2FHWTest__moblab_quick_%2F0%2Fstdout

There's a number of successful builds over an hour, up to right before 90 minutes:

Are people okay reducing the time limit to 90 minutes, at the very slight chance of a false positive (~2h of damage), to save potentially ~7-8h of wasted time before timing out?
