Collection list site packages (#70173) (#72940)

* ansible-galaxy collection list and verify now utilize collections in site-packages.

This is a short term fix for #70147.  The long term fix needs to handle
install (but that discussion is also bound up in how upgrade is going to
work and where things can get installed so it's deferred for 2.11.)

* Add test for ansible-galaxy collection list with site-packages
