MINOR: Revert part of clarifying samples support per os commit

Commit 5c83e3a1563cd7face299bf08037e51f976eb5e3 made some adjustments
to clarify which TCP_INFO information is supported by each respective
OS.

There was a comment like so..

Note that fc_rtt and fc_rttvar are supported on any OS that has TCP_INFO,
not just linux/freebsd/netbsd, so we continue to expose them unconditionally.

But the diff didn't do so in a consistent manner.
