command: simplify OSD property display code

Probably not many user-visible changes. One notable change is that the
terminal OSD code for OSD bar fallback handling is removed with no
replacement. Instead, terminal OSD gets the same text message as normal
OSD. For volume, this is ok, because the text message is reasonable.
Other properties will look worse, but could be adjusted, and there are
in fact no other such properties that would be useful in audio-only
mode.

The fallback message for seeking falls away as well, but that message
was useless anyway - the terminal status line provides all information
anyway.

I believe the show_property_osd() code is now much easier to follow.
