util: adjust 'datapath' to be correct in a frozen OS X package

Apparently unlike py2exe, py2app copies the Mercurial source tree as-is to a
Contents/Resources subdirectory of an app bundle, and places its binary stub in
Contents/MacOS.  (The Windows install has the 'hgext' and 'mercurial' modules in
'lib/library.zip', while the help and templates subdirectories have been moved
out of the mercurial directory to the root of the installation.  I assume that
the python code living in a zip file is why "py2exe doesn't support __file__".)
Therefore, prior to this change, Mercurial in a frozen app bundle on OS X would
go looking for help *.txt, templates and locale info in Contents/MacOS, where
they don't exist.

There are only a handful of places that test for frozen, and not all of them are
wrong for OS X, so it seems wiser to handle them on a case by case basis, rather
that try to change mainfrozen().  The remaining cases are:

  1) util.hgexecutable() wrongly points to the bundled python executable, and
       affects $HG in util.system() launched processes (e.g. external hooks)
  2) util.hgcmd() wrongly points to the bundled python executable, but it seems
       to only affect 'hg serve -d'
  3) hook._pythonhook() may be OK, since I didn't see anything outrageous when
       printing sys.path from an internal hook.  I'm not sure if this special
       case is needed on OS X though.
  4) sslutil._plainapplepython() is OK, because sys.executable is not
       /usr/bin/python, nor is it in /System/Library/Frameworks
