docs/qapidoc: linting fixes

This restores the linting baseline in qapidoc. The order of some imports
change slightly here due to configuring isort a little better:
previously, isort was having difficulty understanding that "compat" and
"qapidoc_legacy" were local modules because docs/sphinx "isn't a python
package". Configuring this manually, isort chooses a different import
ordering, which _is_ intentional here.

Also: extra ignores are added for pylint. The most recent versions of
pylint don't require these ignores, but the oldest versions we support
do, so in the extra ignores go.
