Bintool.version already contains everything required to get the version out of mkimage binary so let's not override it with its own implementation. Signed-off-by: Quentin Schulz <quentin.schulz@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>

This bintool supports running `mkimage` with some basic parameters as

Normally binman uses the mkimage built by U-Boot. But when run outside the

U-Boot build system, binman can use the version installed in your system.

Support is provided for fetching this on Debian-like systems, using apt.
