Remove Setuptools obsolete zip_safe flag

[hugovk]

https://setuptools.pypa.io/en/latest/deprecated/zip_safe.html says:

The zip_safe flag is a setuptools configuration mainly associated with the egg distribution format (which got replaced in the ecosystem by the newer wheel format) and the easy_install command (deprecated in setuptools v58.3.0).

It is very unlikely that the values of zip_safe will affect modern deployments that use pip for installing packages. Moreover, new users of setuptools should not attempt to create egg files using the deprecated build_egg command. Therefore, this flag is considered obsolete.
