package/mender-grubenv: fix grub module checks
PATCH v2 1/1 package/mender-grubenv: fix grub module checks
Commit 3efb5e31fc05705ce3c46b1f0ec031978a5cfab6 broke mender-grubenv by splititng up BR2_TARGET_GRUB2_BUILTIN_MODULES and BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI. Indeed, when a user now builds a system with EFI, the MENDER_GRUBENV_MODULES_MISSING list always returns a full list of grub modules, resulting in the error condition on line 46 to trigger.
In addition, BR2_TARGET_GRUB2_BUILTIN_MODULES has been renamed to BR2_TARGET_GRUB2_BUILTIN_MODULES_PC, so this is changed in mender-grubenv.mk as well.
Add an ifeq that checks if BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI is not empty, and checks the required modules properly if it is not.
---
changes v1 -> v2:
- Change ifeq ($(BR2_TARGET_GRUB2_X86_64_EFI),y) to
ifneq ($(BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI),) to cover all grub2 efi
scenarios. (Thomas) - Change BR2_TARGET_GRUB2_BUILTIN_MODULES to
BR2_TARGET_GRUB2_BUILTIN_MODULES_PC (thomas)

Now that I further think of this, I think this is still not correct. Indeed, one of the major change recently brought to the grub2 package is the ability in a single configuration to have grub support for x86 PC (legacy BIOS) x86 EFI. So in fact you can have BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI and BR2_TARGET_GRUB2_BUILTIN_MODULES_PC non-empty at the same time.
So if you want to do the right thing, you would have to check that BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI doesn't miss any of the mandatory modules if one of the EFI grub2 variant is selected *and* check that BR2_TARGET_GRUB2_BUILTIN_MODULES_PC doesn't miss any of the mandatory modules if one of the legacy BIOS grub2 variant is selected.
