Switch to collections.abc.*

The abstract base classes previously defined in 'collections' were moved
to 'collections.abc' in 3.3. The aliases will be removed in 3.10.
Preempt this change now with a simple find-replace:

  $ ag -l 'collections.($TYPES)' | \
      xargs sed -i 's/\(collections\)\.\($TYPES\)/\1.abc.\2/g'

Where $TYPES is the list of moved ABCs from [1].
