stop.pl tries to stop ns1 via rndc but fails to find rndc.conf because
the logfileconfig test code is unexpectedly executed from the
logfileconfig/ns1/ directory. Instead of stopping ns1 with rndc, it
waits for 30 seconds and then terminates ns1 with the TERM signal.
I:logfileconfig:testing default logfile using named -L file (9)
rndc: ../common/rndc.conf does not exist
Stopping ns1 with rndc was recently inadvertently introduced in
172826bfa8. Stop ns1 with the TERM signal
directly, as we did before.
