shelve: move mutableancestors to not be a closure

There's no value in it being a closure and everyone who tries to read
the outer function code will be distracted by it. IMO moving it out
significantly improves readability, especially given how clear it is
what mutableancestors function does from its name.

#require test-repo slow osx osxpackaging

  $ . "$TESTDIR/helpers-testrepo.sh"

  $ OUTPUTDIR=`pwd`
  $ export OUTPUTDIR
  $ KEEPMPKG=yes
  $ export KEEPMPKG

  $ cd "$TESTDIR"/..
  $ rm -rf dist
  $ make osx > $OUTPUTDIR/build.log 2>&1
  $ cd $OUTPUTDIR
  $ ls -d *.pkg
  Mercurial-*-macosx10.*.pkg (glob)

  $ xar -xf Mercurial*.pkg

Make sure the built binary uses the system Python interpreter
  $ bsdtar xf mercurial.pkg/Payload usr/local/bin
Use a glob to find this to avoid check-code whining about a fixed path.
  $ head -n 1 usr/local/b?n/hg
  #!/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python
