core: Clean up OSD seek info logic

Clean up the code and make the behavior more consistent. Before
bits of the OSD information were triggered in different places, and
various property commands that affect playback position only showed
the seek bar while the main seek command also triggered showing the
percentage in OSD text. Now only the seek and chapter commands trigger
all information and others nothing (which is consistent with most
property behavior).
