cpu: create an empty file when no microcode files are given
Having an empty microcode file makes it more easy to debug
in comparison to a not existing file in cbfs. There are some
platforms (e.g. ep80579) which support microcode updates but
not having any microcode updates yet in our tree.
These platform hang the build because `cat` is called with no
parameters.
