Ignore accidentally tracking xbboot build products. Do track
Makefiles that are not automatically generated. Fixing this makes
debian/clean.sh work again.
Mistakenly ignored files were detected by
git ls-files -i --exclude-standard
and un-ignored build products by
git ls-files -o --exclude-standard
