[OE-core] [PATCH] lib/oeqa/runtime: cleanup and improve output readability for some tests

[Stefan Stanacar]

date:
   - move everything in the same test. setUp/tearDown aren't quite
the right thing here, everything it's part of the same test. (and
it get's confusing when ssh fails)

ldd:
   - change test name and add output to error message

vnc:
   - remove unnecessary check as there is no point in doing
both ps and netstat. Also improve error output a bit.
