tests/flip_test: robustifications

Browse Source 
- don't yell around about dropped frames on tv connectors (and explain
  why in a comment)
- wait a bit when using a test config that checks for dropped frames before
  starting. Also allow for 1% of fudge, this makes it reliably work
- make the dummy load more variable, took too long on older machines.
