[PATCH] tests: honour HWSIM_TEST_LOG_DIR variable

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

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 honour the new HWSIM_TEST_LOG_DIR environment
variable to make it easier to avoid those problems.
