Today, only one certificate is shipped with infix, it is
selectable in menuconfig. It is also possible to add extra
certificates, useful when using infix as a submodule.
All Infix builds should be signed, but for some test equipment, and
during board bringup, this may be too much of a hassle.

Add support for firmware updates via RAUC on aarch64. The created RAUC
bundle (images/infix-$BR2_ARCH.pkg) is signed with the same key used
to sign the raw FIT image.
Ensure that whenever U-Boot is built:
- The chosen signing key and is converted to the expected format and
installed in the build tree.
- Infix's environment extensions are installed in the build tree
