keycam: register under SOP and hide the current node's wireframe

Clicking a non-display node in the network editor drew its output as a
white wireframe over the display node while keycam was active. That is
Houdini's Current Model display set, switched on whenever a SOP state
enters; hou.SceneViewer.showCurrentSopGeometry(False) turns it off, but
only inside a state whose home category is SOP. Keycam was registered
under Object with SOP as an extra context, so the call was a no-op.

Register keycam under SOP with Object as the extra context, call the
flag in onGenerate, and rename the hotkey symbols from state.obj.keycam
to state.sop.keycam to match.
