meta-oe: fix the install dir for udev rules and files

When enable multilib, some packages try to install udev rules and
related files into /lib64/udev/ directory. But these files should
be installed in /lib/udev/ directory even on multilib.
Use ${nonarch_base_libdir} instead of ${base_libdir} to fix it.
