meson nit: deal with warning about future of run_command

WARNING: You should add the boolean check kwarg to the run_command call.
         It currently defaults to false,
         but it will default to true in future releases of meson.
         See also: https://github.com/mesonbuild/meson/issues/9300

In almost all cases we already check the return code explicitly
and throw a more descriptive message than what would be the default.
