Build custom packages with cuirass.

[Mathieu OTHACEHE]

Hi,

I'm trying to use cuirass to build all the packages of my current
manifest on top of guix master periodically.

Some of my packages are custom, so I need cuirass to be aware of
GUIX_PACKAGE_PATH env variable.

The only way I found is to patch cuirass service (cf. following patch).
Is this a good idea ? Is someone doing this kind of stuff here ?

Thank you,

Mathieu
