Subject: [PATCH] grub-install on EFI if forced

UEFI Secure Boot requires signed grub binaries to work, so grub-
install should not be used. However, users who have Secure Boot
disabled and wish to use the command should not be prevented from
doing so if they invoke --force.

fixes bz#1917213 / bz#2240994
