sshpeer: run the ssh command unbuffered
This is necessary to use non-blocking IO base on polling. Such polling is
needed to restore real time output with ssh peer.
Changeset fce065538bcf is talking about 5x regression on Mac OS X when playing
with this value. So we introduced our own buffering layer in previous
changesets. This seems to keep the regression away (we are even issuing much
less read).
