documentation/poky-ref-manual/ref-varlocality.xml: YOCTO #1104 EXTRA_IMAGE_FEATURES

YOCTO #1104: The section describing the local configiuration file
local.conf lists out variables used.  One variable it had in there
was IMAGE_FEATURES.  This variable is not in local.conf.  But,
EXTRA_IMAGE_FEATURES is the variable that is there.  I corrected this.
