This reverts commit ac32d7b87f4d4b546eea96b9b722e88fdb3a5b49.

The new patch resolves the layering violation by simply not trying to look if
`dot` was installed. This is consistent with what we do other extensions.

After this patch we will need `sphinx.ext.graphviz` extension (part of the `dot`
package) which is available via anyway if we build the doxygen-based
documentation.
