Correct snappy-remote port

[Daniel Holbach]

<mattyw> dholbach, hey there, just looking at your email about improving the snappy docs, I was about to submit a bug for a nitcpick, but I thought I'd ping instead
<mattyw> dholbach, the instructions for snappy-remote on this page https://developer.ubuntu.com/en/snappy/tutorials/build-snaps/ states 8022 for the port to use in ssh, but that's only the port used when doing the redirecting described using the kvm image. I'd be tempted to state explicitly that the port would just be 22 if you were using it directly

<sergiusens> mattyw: dholbach more to the point, not putting a port defaults to 22
