Packages must not write anything to $HOME during build.

To enforce such policy, sbuild sets $HOME to /sbuild-nonexistent.
You can see this in the full build log I provided and also in each
and every build log in buildd.debian.org. This way, packages
trying to write to $HOME will fail and we know they have a bug.

If you set $HOME again to the original $HOME, it may or may not work,
but if it fails, it's not my fault, since it's a policy violation.

I offered a VM to reproduce, and the offer still holds, please contact me
privately for details.

Thanks.
