bitbake: cookerdata: Rename BBPKGS -> BBTARGETS

BBPKGS is a confusing name from before we tried to straighten out our
terminology. Its also a mostly unknown variable that isn't in wide use.

I've been asked about it recently and before people start relying more
heavily on it, I'd like to rename it BBTARGETS which better describes
what it does. Its not currently in the manuals, I'd prefer to document
it under the better name. I've not provided any migration path for the
variable since I believe its unused currently.

It allows the targets to built to be specified from a conf file in
addition to those on the commandline.
