[Bug backends/24488] ebl_openbackend might use wrong library search path

Yes, I believe that also makes sense. Certainly for the "native" backend. But
maybe for all. Note that DTS does this (to make static linking possible, so
things work without the backend shared libraries being installed). But it is a
bit of an ugly hack atm. See the mjw/RH-DTS branch. It might make sense to
clean that up and maybe make it configurable which backends are built in.

Still it would be helpful to better understand how the dlopen search path and
substitutions work on Debian based systems.
