Subject: [PATCH] screenshot: Hide screencast button when recorder is disabled

The screencast D-Bus service that is used for the recordings
is only installed if the necessary gstreamer and pipewire
dependencies are found at build time.

The screencast button cannot work when the service is missing,
so don't show it in the first place.
