build: replace ninjatool with ninja
Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion. Instead, we can ask Ninja about
the targets it exposes and forward them.
The main advantages are, from smallest to largest:
- reducing the possible namespace pollution within the Makefile
- removal of a relatively large Python program
- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.
- tracking of command lines, which provides more accurate rebuilds
In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.
