ortp: disable SO_REUSEADDR + SO_REUSEPORT
ortp >= 0.24.0 doesn't differentiate between SO_REUSEADDR and
SO_REUSEPORT, and has both enabled by default. The latter means that
we can end up with non-unique port bindings as we will not fail to
bind the same port twice.
This should have caused visible problems not only when operating multiple
osmo-bts on one machine (rare), but also with a single osmo-bts. Once the range
(default 16384-17407 ) wraps, there is a risk of new sockets (for new cals)
colliding with old ones. As two ports (RTP+RTCP) are used per call, this means
every 512 voice calls we expect the BTS to wrap. And from that point onwards
there's a risk of overlapping with previously allocated sockets.
