screenshot: Handle screencast startup failures using special notification
When the screencast fails to start, we currently don't really inform the
user, other than the red screencasting indicator in the panel going away.
Re-use the failure handling paths to also show a notification when the
screencast fails to start. The notification in this case obviously should
not have an action to open a file (there is no file), so make that depend
on whether this._screencastPath is set and unset the path.
