generate debian/patches

If we are running from a git checkout and there are patches on the
branch, (not counting the always-present debian/changelog update
patch, which is always assumed to be at the top of the patch stack)
put them into debian/patches/ as dpatches and remove them from the
source so that what's put into the source tarball is pristine.
