Utils: Replace Environment::isSameExecutable()

... by FilePath::isSameExecutable().

The only non-mechanical case is the use inside QmakeBuildSystem::testToolChain
using a build environment instead of the FilePath's device environment.

This make a difference in theory due to the use of PATHEXT in the actual
check, but I believe the case that someone creates a 'qmake.foo' and
a 'qmake.bar', adds .foo and .bar to PATHEXT and then complains that
there's a warning missing about not-matching mkspecs has zero
likelihood in reality (and will break other places in Creator anyway).
