Scenario "Booting Tails from a USB drive in UEFI mode" is fragile

Happened 30 times in June, 58 for what 2017 logs we had on July 10th.

Test suite can not find the kernel boot command line, and loop over reseting the VM as expected, but eventually fails. Could it be that we need to wait a bit more longer for the UEFI firmware to boot?

Attaching typical mkv and debug.log.
