checkpatch: Ignore LINE_SPACING

The newest checkpatch version now flags code such as

    int i;
    for (i = 0; ...

because there is no blank line between a declaration and the next
statement. We have always allowed variable declarations inline with the
code in coreboot and libpayload, so this doesn't make much sense for
us. Add it to the ignore list.
