Dominik Riebeling b2380b535e voicefont: make format version a parameter. 
Make hardcoded format version a parameter to allow adjusting depending on the
installed Rockbox version. Rockbox Utility will read the version from the
installed version. Since the command line voicefont tool is only intended for
use in the current tree it uses a fixed version.
