Add sctp authentication to sctp_lib
This only works for linux >=5.4. When enabled, it will use
a shared key to authenticate messages. The functionality is
controlled by a flag and behind a linux version check.
Performance degradation is minimal, even for smaller messages
and unnoticeable when measuring overall system performance.
