* The sandbox must not use an arbitrary file name bootsbox.efi but the
  file name matching the host architecture to properly boot the respective
  file. We already have an include which provides a macro with the name of
  the EFI binary. Use it.

* The path to the EFI binary should be absolute.

* The path and the file name must be capitalized to conform to the UEFI
  specification. This is important when reading from case sensitive
  file systems.

This is supposed to be supported by the 'bootflow cmd' command, at
least according to the help. There is a 'bootflow cmd clear' but it is
often more intuitive to use 'bootcmd cmd set' with an empty value.

Update the command to pass BOOTFLOWCL_EMPTY in this case.

Return an error when the user does not select an OS, so we know whether
to boot or not.

Move calling of bootflow_menu_run() into a separate function so we can
call it from other places.

Expand the test to cover these cases.

Add some documentation also, while we are here.
