reinstall_ndctl.sh: configure and setup in just one step

There is no good reason to:

1. `meson setup` with default options
2. `meson configure -D...` with custom options

... in two separate steps. It has worked so far but that makes it
impossible to address issues like:

```
Program asciidoctor found: NO

meson.build:154:15: ERROR: Program 'asciidoctor' not found or not executable
```

https://mesonbuild.com/Commands.html#configure says:
"Changes options of a configured meson project"

Fixes commit d478476 ("run_qemu: build ndctl during mkosi post-install")
