Yann E. MORIN da9dcddff1 package/mosquitto: requires cmake >= 4.3 ...

With an older cmake version, like the 3.25.1 as available in the docker
reference image, mosquitto fails to build when ccache is enabled:

    [ 98%] Building CXX object lib/cpp/CMakeFiles/mosquittopp.dir/mosquittopp.cpp.o
    In file included from [...]/buildroot/output/build/mosquitto-2.1.2/lib/cpp/mosquittopp.cpp:17:
    [...]/buildroot/output/host/opt/ext-toolchain/i686-buildroot-linux-gnu/include/c++/15.1.0/cstdlib:83:15: fatal error: stdlib.h: No such file or directory
       83 | #include_next <stdlib.h>
          |               ^~~~~~~~~~
    compilation terminated.

Officially, mosquitto only requires cmake 3.18, but that proves to not
be enough, in fact...

We workaround that by requiring cmake 4.3, which is the one version that
could be tested with our host-cmake.
