BaseTools/BuildEnv: Add BinWrappers/PosixLike in PATH
BaseTools/BuildEnv: Add BinWrappers/PosixLike in PATH

As before, we add a directory based on 'uname -sm' into
the path, but now we follow it with
BaseTools/BinWrappers/PosixLike. Since PosixLike is added
later in PATH, the 'uname -sm' path will take precedence.
