tests: protect test libs against multiple inclusion
* t/ax/test-lib.sh, t/ax/am-test-lib.sh: Return early if already sourced.
Use the witness variables '$test_lib_sourced' and '$am_test_lib_sourced',
respectively, for this purpose.
* runtest.in, Makefile.am (AM_TESTS_ENVIRONMENT): Unset 'test_lib_sourced'
and 'am_test_lib_sourced', to avoid interferences from the environment.
