wgengine/netstack: disable RACK on all platforms
The gVisor RACK implementation appears to perfom badly, particularly in
scenarios with higher BDP. This may have gone poorly noticed as a result
of it being gated on SACK, which is not enabled by default in upstream
gVisor, but itself has a higher positive impact on performance. Both the
RACK and DACK implementations (which are now one) have overlapping
non-completion of tasks in their work streams on the public tracker.
Updates #9707
