[OE-core] [PATCH 3/3] LTP: prio-wake- eliminate deprecated usleep calls

[Gary S. Robertson]

From: "Gary S. Robertson" <gary.robertson at linaro.org>

Minor cleanup on realtime test prio-wake.
Replaced deprecated usleep calls with calls to rt_nanosleep,
which has no potentially adverse interactions with signals.
