Bug#972724: dh_missing: allow dealing with manually (cp commands in d/rules) installed files

Hi

sometimes we need to install files depending on the architecture, so
some files are *not* installed on a subset of the architectures (example
kdeplasma-addons).  This seems to be impossible with dh_install's .install
files, so what we are doing is copy the files in d/rules.

But these files are not seen by dh_install because it only checks the
logged files, and not the *actually* installed files

(BTW **why** does dh_missing not compare the actually installed files in
debian/$package/ against the files in debian/tmp, and instead relies on
all helpers correctly updating the list of installed files? This seems
rather error prone as we see).

Of course I can stash them into d/not-installed, but that sounds wrong,
since these files **are** installed, only not via a debhelper tool.

Best

Norbert
