Subject: [PATCH] tests: Let run_tests.sh run Python tests without Makefile
 assistance

Currently run_tests.sh needs the $PYTHON environment variable set to
correctly run pylibfdt tests.  The Makefile does this for make check, but
it breaks if the script is run manually.  Add a fallback to handle that
case.
