Disable pylint warnings for unknown members

For some reason pylint can't determine, that the members are calculated
upon runtime and complains. This is weird as the same mechanism works on
opcode/objects. I haven't found the issue for it yet, so let's just
ignore the warnings for now.

This is a separate patch for easier revert later on, once it's fixed.
