Subject: Runscript: allow extra_commands to be run in chroots

The commands defined in the extra_commands variable do not depend on
whether the service is stopped or started, so it is valid to run them in
chroot environments.

Also, add a note to the runscript man page about the commands in
extra_commands being able to run whether or not the service is started.
