When I try "guix install eog-plugins", it fails to build because
RUNPATH validation fails. Please see the attached log.

The library "libeog.so" is in the "eog" package, which is already among
the "eog-plugins" inputs, but for some reason "...-eog-42.3/lib" is not
in RUNPATH.

$ ls /gnu/store/qhr6hz8cmqq213zyp2z4spdgrkmxvg34-eog-42.3/lib/eog
girepository-1.0/  libeog.so  plugins/

All of "eog-plugins" dependencies build successfully:
