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.

[Yocto #9253]
