[PATCH v3 05/14] test/timer: scale test based on number of cores

[Stephen Hemminger <stephen@networkplumber.org>]

With large core system this would end up taking too long and
test would time out. Scale the number of timers based on
the number lcores available.

Fixes: 50247fe03fe0 ("test/timer: exercise new APIs in secondary process")
