contrib: require Python 3.6 for byteify-strings.py

This script makes use of `token.COMMENT`, which apparently
isn't present until Python 3.6. So make the script and its
test conditional on Python 3.6.

  $ hg init

  $ echo a > a
  $ hg ci -Ama
  adding a

  $ hg an a
  0: a

  $ hg --config ui.strict=False an a
  0: a

  $ echo "[ui]" >> $HGRCPATH
  $ echo "strict=True" >> $HGRCPATH

  $ hg an a
  hg: unknown command 'an'
  (use 'hg help' for a list of commands)
  [255]
  $ hg annotate a
  0: a

should succeed - up is an alias, not an abbreviation

  $ hg up
