Allow script to be run without -z option

I switched to using a temporary directory for the test run, but never wrote a way to use the existing bad tests. Now it just copies the bad tests to ##all## and runs them there.

Should I rename this script? ##tools/zend_tests.py## or something?

hphp/tools/import_zend_test.py
