lualoader: add be-list and be-switch commands

This is useful for driving BE changes from the loader command prompt,
rather than having to use the menu.  Note that the active carousel in
the boot environment carousel doesn't currently reflect a switch in
boot environments done this way- I'm considering this only a minor bug,
as you probably can't or won't go back to the menu if you're using these
commands.
