Subject: [PATCH] tools/record: fix delta times not being relative

Missing last_time assignment caused the delta time between events to be
the total time.

Fixes: a202ed611511 ("Use a newtype usec_t for timestamps for better type-safety")
(cherry picked from commit ad857a51a401d6afa5a1591926e69b8b43ea3579)
