bootmenu: use utf-8 for menu title
The commit a3d0aa87acbe ("bootmenu: update bootmenu_entry structure")
changes the bootmenu title type from char to u16(UTF16 string)
to support EFI based system. If EFI_LOADER is not enabled,
printf("%ls") is not supported, so bootmenu does not appear
correctly.
This commit changes the type of menu title from u16(UTF16) to
utf-8 string and EFI strings is conveted into utf-8.
