[Bug 1689687] [NEW] pass validation if shim protocol is not installed

 

Public bug reported:

GRUB currently fails SecureBoot validation (ie. calls to
grub_linuxefi_secure_validate() fail) if shim's protocol is not
installed when that function is called.

This currently breaks some kernel features relying on starting in the
EFI stub code (ie. the kernel being loaded as an EFI binary); and
instead falls back to the 'linux' command instead of 'linuxefi'.
