qt4: support PyQt4 v4.12.2 where sip became a sub module

https://www.riverbankcomputing.com/static/Docs/PyQt4/incompatibilities.html#pyqt-v4-12-2 :

In previous versions PyQt4 used the copy of the sip module usually installed in
the site-packages directory and applications accessed it using as follows:

  import sip

This version includes a private copy of the module. Applications should access
it as follows:

  from PyQt4 import sip
