Update to latest daq-buildtools needed

[brettviren]

I think listrev must need some kind of update to its cmake files. This cmake function is not found:

daq_point_build_to( src )

Without really understanding what that line does I simply remove it but that leads to another cmake failure:

CMake Error at /home/bv/dev/spack/opt/spack/linux-ubuntu18.04-haswell/gcc-8.4.0/daq-buildtools-1.2.1-mr7qxap4idgujbeohwzv5be6ywzvdwbp/lib/daq-buildtools/cmake/DAQ.cmake:283 (message):
  Error: unable to find needed file
  /srv/bv/spack/stage/spack-stage-listrev-master-p4lajgaftt4jsv5snycjg7vbns7unajo/spack-src/cmake/listrevConfig.cmake.in
  for listrev installation
Call Stack (most recent call first):
  CMakeLists.txt:26 (daq_install)

As the paths imply, this build is done with Spack but I think that is maybe not relevant as cmdlib@master builds after the patch linked in this issue:

DUNE-DAQ/cmdlib#2

and then appfwk@develop installs fine. In any case, testing this with quick-start is blocked for me right now as documented:

DUNE-DAQ/appfwk#116

Hi, the transition to dbt 1.2.x package structure and new cmakelist files should be covered by PR #6.
Please have a look and let us know if something is missing.
