[Telemetry] Improve _GetProcJiffies operation with using grep.
Previously, telemetry read the whole '/proc/timer_list' file just to parse the
first occurence of "jiffies". In case the file is big and telemetry is run
against remote device, this can create a big delay for transferring the file
to host device.
This patch modify it so that telemetry just use
'grep jiffies /proc/timer_list' to get the only lines that contain 'jiffies'.
