socket: fix compat SO_RCVTIMEO_NEW/SO_SNDTIMEO_NEW

socket: fix compat SO_RCVTIMEO_NEW/SO_SNDTIMEO_NEW

It looks like the new socket options only work correctly
for native execution, but in case of compat mode fall back
to the old behavior as we ignore the 'old_timeval' flag.

Rework so we treat SO_RCVTIMEO_NEW/SO_SNDTIMEO_NEW the
same way in compat and native 32-bit mode.
