ipn: remove the preview-webclient node capability

Browse Source 
Now that 1.54 has released, and the new web client will be included in
1.56, we can remove the need for the node capability. This means that
all 1.55 unstable builds, and then eventually the 1.56 build, will work
without setting the node capability.

The web client still requires the "webclient" user pref, so this does
NOT mean that the web client will be on by default for all devices.
