bob-devel depends on bob.buildout but bob.buildout is not included in this package

This looks like a circular dependency issue. The package bob.buildout is a dependence to bob-devel, but is also built during nightlies. As a result, if something happens, we're in a dead-lock situation. For example, we erased the last build of bob.buildout-2.1.5 from the conda channel and now it cannot be easily rebuilt (see, e.g.: https://gitlab.idiap.ch/bob/bob.nightlies/-/jobs/124946).

I wonder if we shouldn't either:

1. Remove bob.buildout from bob-devel, or
2. Move bob.buildout from the nightlies to this package

@amohammadi: please advise.
