[OE-core][wrynose 10/38] grub: disable grub-protect for native builds

From: Himanshu Jadon <redacted>

grub-native fails on hosts where libtasn1 headers are not available
when configure tries to build grub-protect:

  util/grub-protect.c:25:10: fatal error:
  libtasn1.h: No such file or directory

grub-protect is an optional utility for sealing disk-encryption keys
using the TPM2 key protector. It is not used by the GRUB native tools
staged for Yocto recipe execution.

Disable grub-protect for class-native so grub-native does not depend on
libtasn1. This keeps the native build focused on the tools needed by
Yocto and avoids adding another native library dependency only for an
unused utility.

Target and nativesdk builds keep the upstream default, so image and SDK
behaviour is unchanged.
