tcp: tcp: allow SOL_SOCKET-level socket options via sysctl interface

Browse source 
When using the sysctl interface for setting a SOL_SOCKET-level socket
option, the TCP handler refers to the IP handler, which only handles
SO_SETFIB and SO_MAX_PACING_RATE.
So call sosetopt(), which handles all SOL_SOCKET-level options.
Then you can use tcpsso with SOL_SOCKET-level socket options as
expected.
