accel-cmd: improve help message
New users typically use the -h or --help parameters to figure out how
to use accel-cmd. But this only displays accel-cmd options, so users
have no way to learn which accel-ppp commands are available.
This patch improves the help message to introduce the "help" command
which users can use to learn about other accel-ppp commands.
