osmo_dia2gsup: set sndbuf/recbuf explicitly for SCTP

When opening an SCTP socket on Linux, Erlang/OTP does set its own default SO_SNDBUF/SO_RCVBUF values if the respective socket options (sndbuf and recbuf) are not given to gen_sctp:open/N explicitly.

For some reason, the default RCVBUF size (1024) is much smaller than the default SNDBUF size (65536), and both are well below modern Linux defaults. Such a small RCVBUF size becomes problematic when the remote peer is sending large packets.

Let's explicitly set both sndbuf/recbuf parameters to 65536, allowing the user to overwrite this default via the environment parameters.

For more details, see https://github.com/erlang/otp/issues/9722.
