libzeep update

["Maarten L. Hekkelman" <maarten@hekkelman.com>]

Hi,

Just fixed the control file for libzeep, it contained a 
Build-Depends-indep line but apparently this was not a smart move, it 
makes the autobuilder stop at the configure step since it is missing tools.

I also took the liberty to add mrc as a dependency, now that it is included.

I tried to add a autopkgtest, but it is not as simple as adding a script 
calling 'make test'. Tried that, but then I need to rebuild everything 
first again, or I need to patch my makefile. Will do that next time.

regards, -maarten
