[OE-core] [PATCH v2] u-boot: Add mkenvimage tool

[Alexey Brodkin]

This utility is used for creation of images containing
usable in run-time U-Boot environment.

Note it is already gets built with "make tools" command
together with "mkimage" so we just need to install "mkenvimage".

As of today this utility is added per-board like here [1]
for Intel Edison board.
