Added an "ignore" argument to the circular_includes script. This allows the caller to specify files for the script to ignore when it parses the source file. Rather than creating a special ignore case for "kernel_all.c" in the script itself, the user parses the file as an argument (plus others if needed). Updated the kernels cmake file to reflect the change.
