bitbake: lib: Clean up various file access syntax
Python 3 is stricter about how files are accessed. Specficially: * Use open(), not file() * Use binary mode for binary files (when checksumming) * Use with statements to ensure files get closed * Add missing file close statements (Bitbake rev: 9f08b901375ba640f47596f1bcf43f98a931550f) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
