ucert needs to check the firmware part with metadata, but without the signature.
Use the new fwtool mode to extract that without altering the firmware image inside
the check

This reverts commit 41770add03.
The fwtool_check_image() procedure is used by `sysupgrade --test` which must
not alter the image under test in any way.
Currently, when the LuCI ui or any other sysupgrade wrapper first invokes
sysupgrade --test to verify the compatibility of the image and then calculates
the sha256sum over it, the resulting checksum will differ from the original
image since the test invocation will implicitely strip the metadata trailer.
To properly fix the underlying issue, the combined image checksumming code
must be modified to skip the metadata trailer.

If I create following image:
define Device/engenius-m36
IMAGE/sysupgrade.bin := combined-image | append-metadata
endef
Sysupgrade then errors out:
Invalid image. Contents do not match checksum (image:cd285595eaf297370404ae0e2815ec1a calculated:2cf9a2286fb6b01af3ea189128017d44)
Image check 'platform_check_image' failed.
By removing the metadata from the image I get combined-image checksum
working again and sysupgrade works.

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.

this feature has never worked, the fw image name was not passed and the -t
parameter was missing in the tool invocation. drop the feature.

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.
