[bug #45853] Fix iPXE support

[Vít Ondruch]

Follow-up Comment #6, bug #45853 (project grub):

I am trying this on my Lenovo T440s with (only) EFI boot enabled. The default
system in use is Fedora 22 x86_64. Bellow are the steps I am doing:

# rpm -q grub2
grub2-2.02-0.16.fc22.x86_64

# cd /boot/

# ls -la
