gsmtap_util: make sure SO_REUSEADDR is applied for GSMTAP

When gsmtap adding a new sink it does not supply OSMO_SOCK_F_UDP_REUSEADDR
in order to have SO_REUSEADDR applied. In most cases, the gsmtap sink is
just receiving packets to toss them immediately, so having one of them
is sufficient.  However, in other use cases - particularly virt_phy -
we actually want to receve and process GSMTAP messages via multicast
Applying SO_REUSEADDR (like we did before disabling it globally for UDP
in I4a8ffb8d598aca88801a4a0322944d7cdd8d4047 on August 1st) resolves
the issue.
