build-sys: generate CLEANFILES from EXTRA_DIST

Everything that is generated can be assumed to belong to CLEANFILES,
which means that the original file has to be in EXTRA_DIST. Simplify
the rules by generating as in $subject.

We have less lists to adjust manually, and 'make clean' actually
removes more stuff that before.
