Currently os-brick that glance_store depends on uses oslo-privsep
to execute commands with root privileges, so we do not need to
maintain each command for os-brick in the rootwrap filters, but
only need to add the privsep-helper command.
This replaces the filters for os-brick with the privsep helper.

To cleanly utilize devstack's configure_rootwrap function to
install rootwrap config files, these should be placed in
etc/glance/ directory as nova and cinder do.
