efi_loader: correct CTRL-A - CTRL-Z console input
In the extended text input protocol CTRL-A - CTRL-Z have to be signaled as Unicode characters a-z or A-Z depending on the shift state and not as 0x01 to 0x1a. Update Python unit test. This patch is required for using the EFI shell `edit` command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
