Bug#887679: kcoreaddons: please version doxygen B-D per CMake check

["Aaron M. Ucko" <ucko@debian.org>]

Source: kcoreaddons
Version: 5.37.0-3
Severity: important
Justification: fails to build from source (but built successfully in the past)
User: debian-powerpc@lists.debian.org
Usertags: powerpcspe

Builds of kcoreaddons for powerpcspe (admittedly not a release
architecture) have been failing lately:

  CMake Error at /usr/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
    Could NOT find Doxygen: Found unsuitable version "1.8.12", but required is
    at least "1.8.13" (found /usr/bin/doxygen)

Please version its build dependency on doxygen accordingly.  (FWIW,
doxygen's own build dependencies have been uninstallable on powerpcspe
for a while due to issues with the Ruby stack.)

Thanks!
