[PyQt] PyQT/SIP Haiku port

[Zoltán Mizsei]

Hi,

i'm with the HaikuPorts team here, and would like to upstream our 
patches, originally from me, but other porters made also some changes 
in it.
You can find our ports, current recipes and patches here:

SIP: https://github.com/haikuports/haikuports/tree/master/dev-python/sip
PyQT: https://github.com/haikuports/haikuports/tree/master/dev-
python/pyqt

Our current Qt port is: 5.12.2
The current Python port is: 2.7.15 and 3.6.7 (3.7 is in the pipeline 
already)
The current PyQT port is: 5.12.1
And SIP is: 4.19.15

Question: do i have to create a diff, or a PR somewhere, or could you 
guys just pull our patches?

Thanks and best regards,
