[XS] Change in ...osmo-s1gw[master]: sctp_{client,server}: set sndbuf/recbuf explicitly

Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/erlang/osmo-s1gw/+/40019?usp=email to look at the new patch set (#2). Change subject: sctp_{client,server}: set sndbuf/recbuf explicitly ...................................................................... sctp_{client,server}: set sndbuf/recbuf explicitly For some reason, Erlang/OTP does overwrite the OS-default SO_SNDBUF/SO_RCVBUF values even if the respective socket options are not given to gen_sctp:open/N explicitly. Even worse, the receive buffer size is set to a very low value (1024), resulting in major performance issues when dealing with large packets. Set both sndbuf/recbuf to 65536 explicitly - this is the value that Erlang/OTP sets for the sndbuf by default. Allow tuning sndbuf/recbuf via the environment variables.
