py3: don't run source transformer on hgext3rd (extensions)

It's unclear why the source transformer runs on hgext3rd. It's been
like that since it was introduced in 1c22400db72d (mercurial:
implement a source transforming module loader on Python 3,
2016-07-04), and that commit didn't say anything about it (but it says
that it doesn't have "support [...] for extensions").

I find that the current handling of hgext3rd just makes it harder to
convert extensions to Python 3. It makes you convert a bunch of
strings passed to getattr() and kwargs[] to r'' that could otherwise
have been left alone. It's also really confusing that the source
transformer runs when you import the extension as "extensions.foo=",
but not as "extension.foo=/some/path".

I suppose there is small number of (very simple) extensions that would
have worked without this patch that would now be broken. It seems okay
to me to break those.
