sandbox: Add 'sb' command to access filesystem features
The new 'sb' command is intended to deal with sandbox-specific features that have no parallel in other archs. This commit adds two sub-commands to list a directory and read a file from the host filesystem. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
