TT#182450 manage /var/spool/rtpengine in rtpengine-daemon

/var/spool/rtpengine is used by the main daemon as well as the recording
daemon. The recording daemon is not really useful without the main
daemon, while it's perfectly fine to use the main daemon without the
recording daemon. That directory should therefore be managed by the main
daemon package.

This fixes a broken systemd unit stemming from a missing directory if
the recording daemon is not installed.
