FIT signature support in uboot-tools is currently broken in buildroot
master due to changes in uboot-tools' Makefile from the big update in
2025.11. This patch fixes the changes by adding missing defines and make
options.
Note that I sent out a content-identical version of this patch a few
minutes ago that had the wrong git author (@yrlf.at instead of the
company email @go-e.com). Please disregard the previous version of this
patch series.

uboot-tools changed how the config system works for tool builds, which
leads to buildroot's configure cmds being wrong / incomplete.
Specifically, the CONFIG_FIT_* macros are now called CONFIG_TOOLS_FIT_*,
while the make options needed to compile FIT signature support are still
CONFIG_FIT_*. Additionally, CONFIG_TOOLS_LIBCRYPTO is needed to link
uboot-tools with FIT signature support correctly.
This patch fixes the issue by adding the new CONFIG_TOOLS_FIT_* defines
to the generated autoconf.h and adding CONFIG_TOOLS_LIBCRYPTO to the
make options.

I double-checked this and it seems like this also needs
`BR2_PACKAGE_OPENSSL_ENGINES=y` to build correctly, since part of
uboot-tools seems to depend on the openssl `ENGINE_*` family of functions
now when FIT_SIGNATURE support is enabled.
