The dpkg_hurd you need for hurd_install

[Marcus Brinkmann <Marcus.Brinkmann@ruhr-uni-bochum.de>]

Hello,

I am a bit stupid today. You _need_ dpkg_hurd v0.3.1 for the hurd_install
script, and it is useful anyway, so here it is.

In future,  I will upload those to master.debian.org/~brinkmd/hurd/.

Marcus
