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.
