Handle downstream version additions (#22428)

Some downstreams want to ship multiple versions of ansible (Either to
have multiple ansible versions or to have a version that uses python3.X
and a version that uses python2.x).  When they do this, they append
a version number to the cli scripts in /usr/bin.  This patch will remove
those version numbers before trying to find the ansible python module to
import for this commandline
