efl runtime dynamic lib loading - make errors consistent and useful

so drop trying to appease the openbsd packages and stick to "upstream
so major versions" and let users fix their systems with symlinks. also
report what we are looking for so they have a chance to symlink to
make efl happy.

at some point we should make a single simple runtime lib linker
subsystem in efl so all these errors are reported in the same way,
input libray names are listed in a simple consistent way etc. etc.

for now we have 3 locations in efl that do this and they are roughly
similar. we can unify it later.
