Tag suites missing suite level tags

Changed:
  Added Test Tags on suite level to the suites that did not have tags.
With the tags it's easy to run all the tests, except of ones in
particular suites.

Tested:
  Ran robot, specified a directory (in another run it was top level
suite with --suite option), and passed a few --excluded with suite tags,
made sure the excluded suites did not run.
