Bug#878056: src:spyder: Incomplete list of install dependencies

[Ghislain Antony Vaillant]

Package: src:spyder
Severity: grave
Justification: renders package unusable

Since the upgrade to version 3.2.x, the python{,3}-spyder packages
have an incomplete list of install dependencies. This issue affects the
usability of the spyder{,3} applications, hence the severity of this
bug.

Solutions to this issue are to either list the install dependencies
manually (not great) or ensure setuptools is used for the build so that
dh_python can parse them automatically (much better).
