intel-microcode: Install files in correct directory

The directory layout in the archive from GitHub changed, and contains a
directory `intel-ucode` with the microcode update data files. Missing
this, the files were installed incorrectly:

     /lib/firmware/intel-ucode/intel-ucode/06-03-02

Specify the subdirectory the files should be copied from, so they are
installed correctly directly in `/lib/firmware/intel-ucode`.

Increment revision by one.
