obsutil: sort metadata before comparing in geteffectflag()

This is probably less important now that we dropped Python 2. We do still
support Python 3.6 though, and the dictionaries aren't ordered there either
(that was a big change that came with 3.7).

Still, maybe it's a good idea to sort metadata explicitly.

# A simple script for opening merge conflicts in editor
# A loose translation of contrib/editmerge to powershell
# Please make sure that both editmergeps.bat and editmerge.ps1 are available
# via %PATH% and use the following Mercurial settings to enable it
#
# [ui]
# editmergeps
# editmergeps.args=$output
# editmergeps.check=changed
# editmergeps.premerge=keep
