This PR addresses to things:
a) mkdir without -p
When dual-booting, /boot/efi/boot will already exist.
Then that mkdir without -p causes installer to abort grub2 installation with error.
=> fixed by mkdir -p
b) I might want to keep existing /boot/efi/boot/bootX64.efi
=> Changed by adding a confirmation dialog before overwritting.
Tested confirmation yes and no on amd64 hardened rc7.1
