Fix %Sp expansion in wps

The value returned from sound_get_pitch() was shown assuming that 100%
corresponds to 1000 by skin_tokens.c::get_token_value().  The value
actually is 100*PITCH_SPEED_PRECISION.

Steal the way the callchain from gui_syncpitchscreen_run() to
pitchscreen_draw() in apps/gui/pitchscreen.c formats the value and use it
here for consistency.
