fix(dracut): do not add all lib subdirs to `LD_LIBRARY_PATH` with `--sysroot`

On systems with too many library subdirectories, the current approach causes
`Argument list too long` errors, and the initrd also fails to build.

This patch does not fix the original issue by itself (i.e., libsystemd libs not
found), so all the dracut modules that require libraries stored in
subdirectories must explicitly install them using `inst_libdir_file`, which
already successfully handles the `--sysroot` prefix.
