Add support for distcc

[GuillaumeSeren]

Hey there,
I am using ebuildtester again and it is nice the support for ccache,
but my laptop is only 4 threads and I normally use distcc to speed up compilation (when it works).

I think it could nice to have this feature in ebuildtester, what do you think ?

I will try to prepare a small patch for this.

It sounds a nice idea, although I have some doubts about how much this would help in the case of short-lived containers. It's been some time since I used distributed builds, but I remind that distcc required more configuration and was a little bit more "pickier" than sys-devel/icecream. Is there a reason to prefer distcc over icecream?

@stkw0
Sorry for the delay, yep I think it definitely has a cost in term of dependencies,
but I think it could be useful, the config is not so bad only a file in the /etc/disctcc/hosts

Feel free to open a PR. I think it would be easier to discuss it looking at a potential implementation.
