            Add backward compatibility symlink for update-m1n1

The change to a noarch package moved the the install path for m1n1.bin
from "/usr/lib64/m1n1" to "/usr/lib/m1n1". update-m1n1 unfortunately
hardcodes the former path. Updating update-m1n1 is possible but since
this is a critical part of the bootchain for Fedora Asahi Remix systems
it has to be handled with care. Provide the symlink as backward
compatibility for a while.
This is unfortunately complicated by different build environments for
noarch packages in koji and mock. In mock on aarch64  %{_libdir} still
expands to "/usr/lib64".
