tools/cgroup: iocost_monitor: parse help before importing drgn

Browse source

iocost_monitor.py imports drgn before argparse can handle "-h" or report
argument errors. That makes basic usage help fail on systems where drgn is
not installed.

Parse arguments before importing drgn so the help and argument-error paths
work without the runtime debugging dependency. Normal execution still
imports drgn before reading kernel state.
