Skin engine: respect volume decimalization 

This is basically the same problem as FS#13272, except it happens
on certain themes, eg. rayboradio. The issue only affects targets
with decimal volume levels.

Tested the fix using the rayboradio theme on the FiiO M3K and the
Fuze+ simulator. Volume was displayed correctly on both.
