Verify ucert signature chains in sysupgrade images in case ucert is
installed and $CHECK_IMAGE_SIGNARURE = 1.
Also make sure ucert host binary is present and generate a self-signed
ucert in case $TOPDIR/key-build.ucert is missing.

Use fwtool to extract it, only require metadata to be present if the
platform sysupgrade script sets REQUIRE_IMAGE_METADATA=1
Image metadata is in JSON format and contains a list of supported
devices, along with version information that could be displayed by a UI
later before the actual upgrade happens.
