This is the default list of packages which together with the
corresponding FILES_* variables define what packages with what
content get created.

No, that is plain wrong. The packages will get created but if they get
installed or not is up to the image recipe you are building.

Packages get installed because they are listed in IMAGE_INSTALL
variable of the image recipe or they are RDEPENDS, RRECOMMENDS of
a package which gets installed.

I guess that is the wrong question, yes if you don't want a specific
package you would need to not have it in the PACKAGES variable. 
I think though that I've seen strange things happening when not
having the defaults (-dbg, -dev, ...) though.

However, 

if your install task installs files which you do not want in any package,
then you rather should delete those files before packaging them, i.e.:
do_install_append () { rm -f ${D}/usr/bin/not_to_be_distributed }

if the defaults package files into the wrong package then mess with the
FILES_* variable.
