Russ Cox 9be38a15e4 [release-branch.go1.9] runtime: avoid monotonic time zero on systems with low-res timers
Otherwise low-res timers cause problems at call sites that expect to
be able to use 0 as meaning "no time set" and therefore expect that
nanotime never returns 0 itself. For example, sched.lastpoll == 0
means no last poll.

Fixes #22394.
