Python3 console_scripts file name conflict

[hrudham]

If wheel2deb is used to build a Debian package for a project that has a console_scripts entry point, you may find yourself in a position where you cannot install a package.

For example, the pyjwt package has two existing (official) Debian packages provided: python-jwt, which installs the python2 version, and python3-jwt for the python3 version. Both of these Debian packages create a file in the /usr/bin directory. In the case of python-jwt, this is /usr/bin/pyjwt, and in the case python3-jwt, this is /usr/bin/pyjwt3.

However, when building these packages via wheel2deb, both of them end up creating /usr/bin/pyjwt. This causes problems specifically with the python3 version if the official (or wheel2deb generated) python2 version is already installed:

Unpacking python3-pyjwt (1.7.0-1~w2d0) ...
