grub-efi.bbclass: Fix startup.nsh to work on more EFI revs 

Some revs of the EFI firmware + shell do not automatically setup the
path in a such a way as to execute a binary without an absolute
reference like "FS0:\EFI\BOOT\bootx64.efi".  All the versions that I
have tested work properly by simply calling the binary which is in the
EFI\BOOT directory by name like "bootx64.efi".

The error you see on the console looks like the following:

startup.nsh> EFI\BOOT\bootx64.efi
'EFI\BOOT\bootx64.efi' is not recognized as an internal or external command, operable program, or batch file
Shell>

This patch simply drops the EFI\BOOT for greater compatibility.
