Add --with_dev_pkgs option to build_image.sh to pull in developer debug packages.

Add --with_dev_pkgs option to build_image.sh to pull in developer debug packages. 
This defaults to TRUE when building an image.

This CL moves some developer-only packages from package-list-prod.txt to
package-list-debug.txt and adds support for a comma-separated list of
package lists to build_image.sh.

Actually, I'd like to rename package-list-dev.txt to package-list-build.txt
and package-list-debug.txt to package-list-dev.txt but maybe in another CL.

Also there is a patch from lool that we should grab some stuff from that
can filter the package lists by build architecture. Eventually we will
likely add target-specific package lists as well.

With this change, build_image.sh --nowith_dev_pkgs will build an image
that does not contain niceties such as xterm.
