Subject: [PATCH] tests: Honor HWSIM_TEST_LOG_DIR variable in VM runs

If /tmp has a relatively small size limit, or multiple people run the
tests on the same machine, using the same output directory can easily
cause problems.

Make the test framework honor the new HWSIM_TEST_LOG_DIR environment
variable to make it easier to avoid those problems.
