efi_loader: Remove unconditional installation of file2 protocol for initrd
Up to now we install the EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader only falls back to the cmdline interpreted initrd if the
protocol is not installed.
This creates a problem for EFI installers, since they won't be able to
load their own initrd and start the installation.
A following patch introduces a different logic where we search for an
initrd path defined in an EFI variable named 'Initrd####'.
If the bootmgr is used to launch the EFI payload, we'll will try to match
the BootCurrent value and find the corresponding initrd
(i.e Boot0000 -> Initrd0000 etc). If the file is found, we'll install
the required protocol which the kernel's efi-stub can use and load our
initrd.
