util/scripts/ucode_h_to_bin.sh: Drop disruptive quotes

The double quotes around the remaining shell parameters '${@:2}' causes
that the provided *.h files in $(CONFIG_CPU_MICROCODE_HEADER_FILES),
which is a space separated list, cannot be broken down to every single
file as needed but stay as a single parameter in the for-loop.
Therefore, the called function 'include_file' will get a single
parameter with all files which will lead to a broken C code in
terms of a wrong #include-syntax. This causes the script to fail.

To fix this remove the double quotes which works just fine.
