tests: sanitize: fix mem leaks, clean after tests
Fix various mem leaks in the testing code.
Add test_common_cleanup() in test_common.c, to free talloc contexts; call in
test-{helpers,hnbap,ranap}.c. Upon talloc ctx cleanup, ensure that they are
actually empty, in order to catch newly introduced mem leaks.
If non-empty, print talloc context reports.
