Fix FS#11387 - PictureFlow runs jerkily while playing music on Nano2G after the recent feature addition

The problem r26713 addressed was not caused by missing yields but by too high
priority of the background loader thread. Undoing the yield() change and decreasing
the priority fixes the audio drop as well but doesn't cause jerkiness.
