Pass additional profile to IDE build to ignore known flaky tests

By passing the additional maven profile `skipFlakyTests`, tests that are known
to be flacky are ignored.
Ensure downstream jobs use same sha for mergebranch.

Before, we wrongly did this:

  - build scala from the pr, merged into $mergebranch.
  - [time passes, $mergebranch advances]
  - to run the test suite downstream, merge the pr into $mergebranch

However, new tests may have appeared that fail with the original build of scala.
Thus, serialize the sha for $mergebranch in step 1, use that downstream.
Make publish_scala wipe $LOCAL_M2_REPO/org/scala-lang

We were keeping around all tested (and thus published)
scala versions, so that we ran out of disk space.
Wipe $IVY_CACHE/cache/org.scala-lang on startup.
Put mergetarget in root, jenkins-artifacts is wiped later.
