[settings] Expose exit status of failed command via ${errno}
Allow scripts to report errors in more detail by exposing the most
recent error via the ${errno} setting. For example:
chain ${filename} || goto failed
...
:failed
imgfree http://192.168.0.1/ipxe_error.php?error=${errno}
Note that ${errno} is valid only immediately after executing a failed
command.
