Eliminate major sources of daily noise in SBT build.

  - Intercept incorrect "binary conflict" warning issued by SBT.
    Fixes https://github.com/scala/scala-dev/issues/100
  - Bump to a new version of pantsbuild/jarjar to fix an
    incompatibility with Java 8 parameter names in class
    files, which we run into on the 2.12.x branch. See:
    https://github.com/pantsbuild/jarjar/pull/19
  - Disable info level logging for dependency resolve/download.
