package/owfs: delay sysvinit start until after network and avahi

In its default configuration, owserver opens a TCP socket on the 'lo'
interface. However, in some situations, the 'lo' interface may not yet
be up until S40network is started. This causes owserver not to start its
TCP socket, which makes it impossible for the owfs client to connect to
it.

In addition, owserver may have avahi integration.

Therefore, delay the start of owserver and owfs until after S40network
and S50avahi-daemon.
