Change err_pp_file_not_found back to an Error; when it's a Warning, we suppress it in system headers. And it is not a good idea to suppress it in system headers. (This was originally changed in r134996 to implement -MG.)
Fixes <rdar://10041960>. And also brings down the number of warnings without a flag by one :)
