build-requirements when using the Imagebuilder

[Sven Roederer]

Hi,

based on the recent changes to the tools required when using the imagebuilder, 
I wonder If there are more tools that can be excluded for this case.
Candidates I see here are:
* patch
* unzip
* bzip2
* Perl 5.x (including Data::Dumper, Thread::Queue)
* Python
* Git
* rsync

This list is just guessing and I did not check. Most of this tools are usually 
installed on recent systems per defaul and checking for them will nore harm. 
But Perl and Python might be interesting to exclude from the checks.

Is anyone aware, that these are real requirements for Imagebuilder?


Best Sven
