Because live images don't work properly if it's either disabled or
enforcing while the image is being generated. Why *that* is I don't
know, but before bcl made the livecd-creator script do this, we just had
a bit in the livecd-creator instructions which said "you have to run
setenforce Permissive before starting to build a live image".

If you try building a live image with SELinux either disabled or
enforcing on the build host, you wind up either with a compose that
fails, or an image that can't be booted in enforcing mode.

livecd-creator is a string-and-duct-tape hack, it does quite a lot of
ugly things. bcl's been trying to replace it with livemedia-creator for
a while, but that effort seems to keep running into roadblocks.
