[PATCH] classes/image: allow complementary package globs to be extended

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Make it easy for the wildcard specifications for complementary package
features to be extended outside of image.bbclass. For example, to add a
new "foo-pkgs" item that could be added to IMAGE_FEATURES that would
cause *-foo packages to be installed for all packages currently in the
image, you can now use this line at the global level:

COMPLEMENTARY_GLOB[foo-pkgs] = "*-foo"

Implements [YOCTO #4228].
