  1. doc: Document how to run a subset of regress tests

Hi Victor,

I would recommend using Meson. It's much faster and Autotools support
will be removed in the future.

I have a little cheat sheet on the subject [1]. It's in Russian but
Google Translate will help. For instance you can do:

```
meson test -C build --suite postgresql:test_slru 'test_slru/regress'
```

If you believe there is room for improvement in the official
documentation, patches are welcome.
