cmd: bootmenu: add parameter -e for UEFI boot options

The bootmenu command can display

* menu entries defined by environment variables
* menu entries defined by UEFI boot options

Not in all cases showing the UEFI boot options is desired.
Provide a new parameter '-e' to select the display of UEFI boot options.
