Bug#1024447: Actual problem is grub-efi-amd64-signed is not updated to 2.06-7

[Ralph Martin]

Apologies

On further investigating, the problem is not that 2.06-7 does not fix 
the problem, but rather that on doing an apt upgrade, the 
grub-efi-amd64-signed package remained at 2.06-5 even though other 
grub-related packages were updated to 2.06-7:

grub-common/testing,now 2.06-7 amd64 [installed]
grub-efi-amd64/testing,now 2.06-7 amd64 [installed]
grub-efi-amd64-bin/testing,now 2.06-7 amd64 [installed,automatic]
grub-efi-amd64-signed/testing,now 1+2.06+5 amd64 [installed,automatic]
grub2-common/testing,now 2.06-7 amd64 [installed,automatic]
