scripts:/oe-selftest: Use timestamp instead of test names in coverage data file
This fixes the problem by changing the name to the coverage data file, using the timestamp as an identifier. The name for the coverage data file is constructed based on the tests ran; this has created a couple of issues so far, affecting coverage report. If --run-tests-by option is given, the data file name won't have any identifier, causing following runs to overwrite themselves. On the other hand, if too many tests are given, the file name exceeds linux limits and fails to store the coverage data all together.
