Build scripts and powershell-simple.cs were refactored to work with the
patch to CoreCLR and updated hosting code.
- Paths in Makefile were fixed because the hosting code runs the
assembly from the current working directory (usually app_base)
- runps scripts were all fixed because the hosting code CLI changed
- powershell-simple.cs was cleaned up because its Main function is now
directly executed
- monad submodule was repinned while we had the change
- monad-ext submodule was updated with rebuild CoreCLR binaries
- monad-native submodule was repinned to development, including fixed
test and hosting code changes
