Let's update net-ssh to see if this fixes weird periodic failures.

I think we mainly saw these deployment failures (something about
xserver) on JRuby, and maybe more-so on wifi, so this update is a bit of
a stab in the dark, but given the low-level nature of the errors and
based on the net-ssh changelog, it seems like maybe it might be fixed in
newer versions.
