python3-lxml: Upgrade 4.5.2 -> 4.6.1

Upgrade to release 4.6.1:

- lxml.html.InputGetter supports __len__() to count the number of
  input fields.
- lxml.html.InputGetter has a new .items() method to ease
  processing all input fields.
- lxml.html.InputGetter.keys() now returns the field names in
  document order.
- GH-309: The API documentation is now generated using
  sphinx-apidoc.
- C14N 2.0 serialisation failed for unprefixed attributes when a
  default namespace was defined.
- TreeBuilder.close() raised AssertionError in some error cases
  where it should have raised XMLSyntaxError. It now raises a
  combined exception to keep up backwards compatibility, while
  switching to XMLSyntaxError as an interface.
- A vulnerability was discovered in the HTML Cleaner by Yaniv
  Nizry, which allowed JavaScript to pass through. The cleaner
  now removes more sneaky "style" content.
