Fix compile error in Eclipse 

Let's consider compile/inc/src/main/scala/sbt/CompileSetup.scala.
There are multiple Output types, and according to Eclipse importing
xsbti.compile.Output within the package sbt does not work because the
import is shadowed by sbt.Output.

However, compilation proceeds just fine within SBT. Reproducing the
example however gives the same warning, if the files are in the same
project. The problem here is probably that the shadowing Output
is declared in the same package but in another project, and that seems
to give different results in Eclipse and SBT, but relying on
that looks fragile.
Reading the spec is inconclusive since it doesn't match with Scalac's
behavior — see
https://groups.google.com/d/topic/scala-internals/-Rquc2HBYLk/discussion .

ForkTests has the same behavior as CompileSetup.
