Patch for llvm-lit to look for bash in PATH

llvm-lit disregards PATH environment variable when looking for bash. This is
due to LitConfig.getBashPath always calling Utils.which with a second argument,
even when this is empty. The attached patch checks of self.path is empty and in
that case calls Utils.which with just one argument, making env PATH to be used.
