[bug#58792] [PATCH v2 2/2] gnu: python-virtualenv: Update to 20.16.5.

[Tanguy Le Carrour]

Regarding this patch, I tried and failed updating python-distlib.
I ran into a GPG key issue that I didn't know how to solve.

* gnu/packages/python-xyz.scm (python-virtualenv): Update to 20.16.5.
[arguments]<#:phases>: Add phase compatibility-fixes.
[propagated-inputs]: Add python-platformdirs.
