[PATCH nft v2 2/5] build: add `make check-build` to run `./tests/build/run-tests.sh`

[Thomas Haller <thaller@redhat.com>]

`./tests/build/run-tests.sh` performs a build check. Integrate it in
make as `make check-build` target.

`make check-build` is hooked into `make check-more`, which in turn is
hooked as `make check-all`.

Note that this is intentionally not part of `make check`, because `make
check` is run by `make distcheck`, and the build test itself calls `make
distcheck`. Even if that cycle would be resolved, doing a build check
several times during `make check` seems wrong and would add another
minute to the test runtime.
