buildOctavePackage: add octave.withPackages passthru test

While revieweing a octavePackages PR, an ecosystem I'm not familiar with, I was puzzled to find there was no real install test.
While `buildOctavePackage` does run `octave-cli --eval "pkg build ..."`, it isn't before the user calls `octave.withPackages` that `octave-cli --eval "pkg install ..."` is run.
This PR adds a sniff test that does just that to all octave packages. This test si most often only needed when bumping and adding octave packages, although it would be nice to somehow do this during `installCheckPhase` instead.

While the `self` approach here _works_, this builder ought to be refactored to use `lib.extendMkDerivation` instead, but I leave that for the octave maintainers.

Testing:
