boot/uboot: add BR2_TARGET_UBOOT_USE_BINMAN option

Browse Source 
Recent version of U-Boot use binman to provide a mechanism for building
images, from simple SPL + U-Boot combinations, to more complex
arrangements with many parts.

This tool uses additional host python modules that must be provided by
Buildroot. So introduce a new option BR2_TARGET_UBOOT_USE_BINMAN to
add additional host packages in U-Boot build dependency to use binman.

The binman requirement is directly included in buildman dependency
(tools/buildman/requirements.txt) since within U-Boot, binman is
invoked by the build system, here buildman [1].
