[OE-core] File conflicts between PN-doc packages

[Martin Jansa]

I'm testing changes to allow world-image builds 
https://bugzilla.yoctoproject.org/show_bug.cgi?id=3505

And even with very small subset of oe-core I got a lot of file
conflicts mostly between PN-doc packages.

We can return --force-overwrite to do_rootfs installs, but that 
only moves this issue to end user trying to install e.g. 
util-linux-doc and e2fsprogs-doc.

Do we want u-a used for stuff like doc? 

What about conflicting .debug stuff from console-tools-dbg and kbd-dbg?

We can use:
1) u-a
   + most correct behavior
   - more metadata
2) RCONFLICTS
   + proper message to end user
3) EXCLUDE_FROM_WORLD_IMAGE
   - doesn't test installation for all PACKAGEs just because some are conflicting
4) EXCLUDED_PACKAGES_FROM_WORLD_IMAGE
   + exclude only some items from PACKAGES list
5) some combination of above
   e.g. RCONFLICTS for PN-dbg, u-a for PN-doc

Here is whole list, but be aware that this is only about 2/5 of oe-core, 333 recipes from 826.
