scripts: never exit 1, always call err instead
this same change has been applied, selectively, to certain return statements. the general rule is this: the return statement should only be used to direct logic within a script, where certain non-errors states are used to skip certain actions; the exit command should *never* be used to return non-zero, except by err(). in so doing, we ensure easier debugging of the build system also: strip_rom_image in build/release/roms was running "continue" when a rom file didn't exist, despite not being a while/for loop. i make it return (non-error condition) instead it's ok for a script to exit 0, where appropriate, but perhaps a function could also be written for it Signed-off-by: Leah Rowe <leah@libreboot.org>
