 Refs #10948. Fully randomize EIT crawl start time.

 The deadlocks we've been seeing here should be fixed now, but they
 should have been rare to begin with due to randomization of the
 EIT Scanning start time. But they were occurring at fairly high
 frequency. It turns out we were not applying enough randomness when
 there were multiple cards and we were also losing randomness after
 the first recording on a tuner finished and we reset the clock.
 (cherry picked from commit 0e5d159c6bc98ef29a7b6bb225b43492b45c37ac)
