twisted: updated to 19.7.0 + removed inceremental.path

[goffi-contrib]

Last version is building fine with p4a. Also incremental.patch doesn't
seem needed anymore (using Python 3), I could build without it.

Thanks for the PR, it looks like the patch might be needed at least on Ubuntu somehow, see build error on CI:
https://travis-ci.org/kivy/python-for-android/jobs/600355532

distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('incremental>=16.10.1')

indeed, I've restored the patch.

Thanks!
Build is still failing because that patch probably needs an update now 😕
