#68130: py-pip, py-virtualenv: drop EOL pythons >= 3.4?

 Our current [wiki:Python#VersionPolicy policy] says:
 > The setuptools, pip and virtualenv modules should continue to be
 provided even for EOL Python versions, so that users who need them can
 still install modules.

 However, Python 3.4 and later ship with both `venv` and `ensurepip`, which
 should be sufficient for this purpose. So while the 26 through 33 subports
 will remain necessary, I think it's probably OK to drop the later EOL
 versions as normal provided the subports have no dependents, i.e. 34, 35,
 36, and 37 currently; and continue to do so for future versions as they go
 EOL.

 Thoughts?
