gnu: python-fixtures: Propagate python-pbr.

* gnu/packages/check.scm (python-fixtures-bootstrap,
python2-fixtures-bootstrap, python-testrepository-bootstrap,
python2-testrepository-bootstrap): New public variables.
(python-fixtures): Adjust accordingly.
(python-testrepository): Likewise.
[native-inputs]: Remove PYTHON-PBR-MINIMAL.
* gnu/packages/python.scm (python-pbr)[native-inputs]: Replace PYTHON-FIXTURES
and PYTHON-TESTREPOSITORY WITH PYTHON-FIXTURES-BOOTSTRAP and
PYTHON-TESTREPOSITORY-BOOTSTRAP.
