bash_completion: Use default bash completion for files after `cros`.
The code originally use `compgen -o default` to generate a list of
completion after cros subcommands, which doesn't work well with
directories.
For example, the image is located at "./images/a.bin"
"cros flash imag<tab>" would complete to "cros flash images " currently,
and user have to delete the space, add '/' and press tab again for
completion.
Change it to return nothing, so it would fall back to "complete -o
bashdefault -o default" in this case, and the above case would complete
to "cros flash images/" as expected.
