meson: fix meson warning

Resolve the following:

```
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 meson 2.0.
```

This commit does as meson recommends, and adds check: true to all
run_command calls, which will be the default.
