autoPatchelfHook: Support arbitrary paths in runtimeDependenciesorigin/apeh-anysogitlab.intr/apeh-anyso
Previously, the setup hooks configuration variable only accepted packages
and added lib subdirectory of those packages to rpath.
That was insufficient for including shared libraries like `lib/libv4l/v4l2convert.so`
so this patch allows for passing .so file paths whose parent directory will be added to rpath.
The patch also makes the process more strict, failing when a package not containing lib
or not a .so file is passed to avoid hard to debug failures like passing a wrong output.
