PY3: In a pure PY3 build filter-subunit was getting called without 'python'

tests were getting called with "| ${src}/selftest/filter-subunit" which
resulted in filter-subunit getting execve'd without a calling python. This
resulted in /usr/bin/python (default python) getting called and subsequent
imports failing.
