[PATCH openbmc v5 1/3] Add OBMC_IMAGE_EXTRA_INSTALL variable

[OpenBMC Patches]

From: Brad Bishop <bradleyb at fuzziesquirrel.com>

Prior to this patch packagegroup-core-boot was not being pulled in.
core-boot is what brings in the init_manager (systemd) but
somehow systemd was added as a dependency by OE for the skeleton package
so the missing core-boot packagegroup went unnoticed.

core-boot was not being pulled in because of an assignment to
IMAGE_INSTALL in the global configuration.  Yocto core provides a
mechanism to do the same thing safely - CORE_IMAGE_EXTRA_INSTALL;
use this and also adopt a similar approach for adding extra packages
to image recipes using obmc-phosphor-image.
