efi: libstub: Always enable initrd command line loader and bump version
In preparation for setting a cross-architecture baseline for EFI boot
support, remove the Kconfig option that permits the command line initrd
loader to be disabled. Also, bump the minor version so that any image
built with the new version can be identified as supporting this.
