Using ninja instead of make (1) can lead to significant speed ups while building.
Therefore switch from having the ninja generator opt-in to having it opt-out.
Previously cmake-ports that wanted to use ninja could set
CMAKE_NINJA=yes
now, ports that do not work with ninja can set
cmake:<existing args>,noninja
Note, that needing this should be an exception and most often points to a broken
cmake of the port.
The ports using cmake were modified
* removed USES=gmake, if ninja is used
* removed MAKE_ARGS, if ninja is used
* added the cmake-argument noninja if necessary
