            spec: move all pending EFI logic from common to EFI package

Commit 3212759d (Move the EFI config's stub generation into EFI
posttrans) moved just the stub script generator but not the rest of
the logic related to EFI. Without this change, the EFI config stub was
completely regenerated on every GRUB update, causing cmds to be lost,
e.g. cmds to allow decrypt /boot partition.
