setup.py: prefix fixes

[hanetzer]

Using these patches I end up a proper file list on my gentoo-on-gentoo prefix.

Not ready for merging; needs work to actually work.

Current issue.

2 things:

1. lstrip EPREFIX once, not every time you use it
2. Don't change port_conf in defaults.py, that's what's causing your problem.

[dol-sen]

has something changed? Catalyst must be run as root since it needs to create and use mounts as well as chroot. Is that now possible in an eprefix environment?

[hanetzer]

@dol-sen I've not tried/looked at this in a while, but I could get it to work
in a prefix, yes. No reason you can't install sudo or use su in a prefix, ya
know.
