use the new coding style in scripts
there were stragglers left over from the last audit, and these stragglers still exist even after all the major re-factoring as of late the new style is: bsd-like coding style and error handling. verbose yet simple error handling. we use an "err" function in a way reminiscent of most C programs that you see in openbsd base (err.h) this style is very clean, resulting in readable code Signed-off-by: Leah Rowe <leah@libreboot.org>
