bitbake: data: Optimise flag exclusion list handling
Move the variable lookup to the outer loop for performance, replacing a now unneeded parameter (after the previous changes). (Bitbake rev: 8a59a8707cecbde257fca169775ce8ff7709928b) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
