Instead of letting CMake set RPATH of the test executables, use
INSTALL_RPATH
andBUILD_WITH_INSTALL_RPATH
just like other executable and shared libraries.Previously when a swift module link with exported swift-syntax targets e.g. 'SwiftSyntax::SwiftParser', the libraries in earlyswiftsyntax were used instead of the copied libraries in the swift build directory. That wasn't ideal.
