package/gdb: make version 12.x the default

We can remove the quirk around BR2_or1k: it was there to make sure
that 11.x was the default when no target gdb is selected for all
architectures except or1k, and that 12.x would be used by default on
or1k, as 11.x is not available/broken.

Now that 12.x is the default for everybody, this quirk is no longer
needed. 11.x was already no selectable for or1k, and remains not
selectable.
