Due to the lack of "match-clients" clauses in ns4/named2.conf.in, the
same view is incorrectly chosen for all queries received by ns4 in the
"keymgr2kasp" system test. This causes only one version of the
"view-rsasha256.kasp" zone to actually be checked. Add "match-clients"
clauses to ns4/named2.conf.in to ensure the test really checks what it
claims to.
Use identical view names ("ext", "int") in ns4/named.conf.in and
ns4/named2.conf.in so that it is easier to quickly identify the
differences between these two files.
Update tests.sh to account for the above changes. Also fix a copy-paste
error in a comment to prevent confusion.
