[PATCH] um: time-travel: fix time-travel-start option

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

We need to have the = as part of the option so that the
value can be parsed properly. Also document that it must
be given in nanoseconds, not seconds.

Fixes: 065038706f77 ("um: Support time travel mode")
