Bug#999710: timidity patch 0005-fix-drum-panning.patch appears to be wrong

[Hans de Goede]

A quick follow-up I just noticed this bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987052

Which is complaining about wrong pan with Debian's
timidity and with Fedora's timidty (without the patch)
this problem does not happen.
