dnstap-read.1 manpage installed even when dnstap is disabled
This is a minor issue in 9.16.4, but while building the Ubuntu packages I noticed that the
dnstap-read.1 manpage is being installed by
make install even when
./configure --disable-dnstap (or simple not using
--enable-dnstap) was used. This is a change from bind 9.16.3.
