    meson.build: Be careful with run_command()
    
    See https://github.com/mesonbuild/meson/issues/9300
    
    In some future version of meson, the `check` kwarg of `run_command()`
    will default to `true` instead of `false`, meaning that `meson` will
    error out if the command fails. When we check `.returncode()`, we don't
    want that to happen, so explicitly set `check: false`. If we don't use
    `.returncode()`, we expect the command to succeed, so allowing `meson`
    to error out should be desirable.
