Subject: [PATCH] When pip is run outside of venv, don't show the upgrade
 warning

This is a fix for https://bugzilla.redhat.com/show_bug.cgi?id=1573755

1. We put "rpm" inside pip's INSTALLER instead of "pip"

2. From pip, we check what's in INSTALLER and only show the warning
   if it's "pip".

When a venv is cearted, pip is installed from wheel (trough rewheel),
INSTALLER contains "pip".

When virtualenv is used, pip is installed from the Interwebz via pip,
so INSTALLER contains "pip".
