[VSP-Tests PATCH 3/3] scripts/logger: Use new monotonic-ts tool

[Kieran Bingham <kieran.bingham@ideasonboard.com>]

Utilise the new monotonic timestamping tool to remove the manual parsing of
timestamps via /proc/timer_list which can only be read by root.

This also simplifies the processing required and contains all timestamping
actions within a single process space.
