bitbake: cooker: Ignore KeyErrors during shutdown

When parsing failures occur, trap KeyError to avoid these kinds
of tracebacks (from a parsing error in meta-ti).

bb.parse.ParseError: ParseError at /srv/pokybuild/yocto-worker/check-layer-nightly/build/meta-ti/meta-ti-bsp/recipes-kernel/linux/linux-ti-mainline_git.bb:6: Could not inherit file classes/${KERNEL_BASE_CLASS}.bbclass

During handling of the above exception, another exception occurred:
