test: fix flaky test-make-doc

`test-make-doc` fails in CI on Raspberry Pi devices where `test-ci-js`
runs the test but does not build the docs. We do not want to build the
docs in these cases. Move the test to the `doctool` suite and add that
suite to `IGNORED_SUITES` in `test.py`. Specify `doctool` as a test
suite to run with `make test` or `make test-ci` but not with the
`make test-ci-js` job run on cross-compiled fanned CI tests like we do
with Raspberry Pi devices in CI.
