#67055: Unable to set PYTHONPATH via test.env

 I believe this is a defect in the Python portgroup.

 The `PYTHONPATH` variable is not getting propagated from `test.env` down
 to the actual running of the tests. This is breaking the case where you
 are trying to test against a package that has not yet been installed so
 there's no package in the `PYTHONPATH` to import.

 Attached is a simple portfile to reproduce the issue. Here is the guts of
 the portfile:

 {{{
     python.test_framework \
                     pytest
     test.run        yes
     test.target
     test.env        FOO=bar PYTHONPATH=${worksrcpath}/src
 }}}

 Truncated test output. Note FOO is set, but PYTHONPATH is empty:
