github: add NUM_DOMAINS test matrix

This will now test with the following num_domains settings:

- PRs: default as in config file, no matrix
- push to master: with NUM_DOMAINS = 1 and 16
- weekly test: with NUM_DOMAINS = 1, 7, and 16

16 is the default in the current config files. 1 leads to structural
code changes is the setting most likely to break. 7 is for checking
that the proofs also work with a value that is not a power of 2.
