largefiles: drop repo wrapping detection

After 257afe5489d4 I see:

  $ hg id -q
  largefiles: repo method 'commit' appears to have already been wrapped by another extension: largefiles may behave incorrectly
  largefiles: repo method 'push' appears to have already been wrapped by another extension: largefiles may behave incorrectly
  be207d9b7e4b

The warning is bad:

* The message gives no hint what the problem is and how it can be resolved.
  The message is useless.

* Largefiles do have its share of problems, but I don't think I ever have seen
  a problem where this warning would have helped. The 'may' in the warning
  seems like an exaggeration of the risk. Having largefiles enabled in
  combination with for instance mq, hggit and hgsubversion causes a warning
  (depending on the configuration order) but do not cause problems. Extensions
  might of course be incompatible, but they can be that in many other ways.
  The check and the message are incorrect.

It would thus be better to remove the check and the warning completely.

Before 257afe5489d4 the check always failed. That change made the check work
more like intended ... but the intention was wrong. This change will thus also
back that change out.
