TemporaryUploadedFile.seek function signature doesn't match what's expected

[vomjom]

In django/core/files/uploadedfile.py, TemporaryUploadedFile's seek function only takes an offset, but as in shown in ​http://docs.python.org/lib/bltin-file-objects.html it should also takes a whence argument.

It'd be far better if TemporaryUploadedFile's file-object functions were more similar to InMemoryUploadedFile in that they would pass all the arguments, like:

def seek(self, *args, **kwargs):
    return self._file.seek(*args, **kwargs)

And so on for the rest of the functions.
