Return not supported if no necessary socket option
In order to support tcp keepalive offload, some socket
options are necessary. If one of them isn't supported in
kernel, just return ERROR_HARDWARE_UNSUPPORTED to the
caller.
e.g.
TCP_REPAIR starts from kernel 3.5
TCP_REPAIR_QUEUE starts from kernel 3.5
TCP_QUEUE_SEQ starts from kernel 3.5
TCP_REPAIR_WINDOW starts from kernel version 4.8
Bug: 124453402
Test: -boot, flash, atest FrameworksNetTests
