Etienne Champetier 799de7c641 build: cleanup possibly dangling Python 3 host symlink
When switching from master branch to 19.07 or older, we need to ensure
that Python symlink in staging bin directory points to Python 2.

We can't rely completly just on SetupHostCommand as its executed only in
cases when the $(STAGING_DIR_HOST)/bin/python doesn't already exist, so
we need to remove it before running SetupHostCommand.

This is a cherry-pick of 3b68fb57c9
with python3 instead of python2
