File reproducible.patch of Package blobwars

https://sourceforge.net/p/blobwars/patches/8/ (boo#1041090)

When building blobwars packages for openSUSE, we do so in disposable VMs, which means every build has a new filesystem and thus ordering of files differs for the readdir call in src/pak.cpp

See https://reproducible-builds.org for why this matters.
