OpTestSystem: Increase IPL petitboot timeout to 1000 sec's.

As early debug PNORs will take around 350 seconds to boot the
hostboot, SBE update on both the chips will take around for 100s
and also after PNOR firmware flash hostboot will take
more time(approx 300s) to do memory dianostics based on number
of DIMM's. So this patch increases the timeout to 1000sec's to
avoid TIMEOUT issue after a PNOR FW Flash.
