......................................................................

libvlr: set the correct CN domain

In preparation of splitting up the libvlr code, set the CN domain
on all required GSUP messages which allow the CN domain to be present.

The test cases expect the exact GSUP message. The additional TLV is
280102 (IE: CN domain, length 1, CS (2)).
