create-appimage.sh: do not exclude libpipewire-0.3.so.0

ilibpipewire-0.3.so.0 was added to excludelist causing the distcheck fail,
see [1]

We do not need to exclude the lib, because we already handle the preload
in data/scripts/Linux-AppImage/AppRun:282 (the case is similar as for
libjack.so.0 as also mentioned in the related AppImage issue).
