Werner Zeh 5171960b23 util/scripts/ucode_h_to_bin.sh: Fix .inc-lines with just comment
There are microcodes in .inc format out in the wild which contains
lines with just a comment. So these files look like the following
example:

; External header
dd 000000001h
dd 00000001bh
...
; Data
dd 000000000h
...

The lines with just a comment starts with a ';' and will break
the current awk formatting which is performed to reformat the content
into C code style. As we are just interested in the data we can simply
drop all lines that start with a ';' which sed can do pretty easy.
