bitbake: daemonize/build: Clean up /dev/null fd handling
At the end of bitbake selftest we see: sys:1: ResourceWarning: unclosed file <_io.TextIOWrapper name='/dev/null' mode='r+' encoding='UTF-8'> Clean up the /dev/null handling to drop the unused entry in build.by and ensure the other open() calls are cleaned up. NULL was unused since http://git.yoctoproject.org/cgit.cgi/poky/commit/bitbake/lib/bb/build.py?id=4a081b5a52e3d27da8d4b062f3fda292e8d8fb0a back in 2012. (Bitbake rev: e72be96cfa9f05fda5f420c7cfa8bcfa9304b884) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
