[PyQt] PyQt4 fails to build dbus.mainloop.qt extension with Python 3

[Arfrever Frehtes Taifersar Arahesis]

dbus-python-1.0.0 was released on 2012-01-24 and introduced support for Python 3.

configure.py of PyQt4 needs to be fixed.
iflags is b'-I/usr/include/dbus-1.0 -I/usr/lib64/dbus-1.0/include  -ldbus-1 -lpthread -lrt'
str(iflags) is "b'-I/usr/include/dbus-1.0 -I/usr/lib64/dbus-1.0/include  -ldbus-1 -lpthread -lrt'"
str(iflags).split() is ["b'-I/usr/include/dbus-1.0", '-I/usr/lib64/dbus-1.0/include', '-ldbus-1', '-lpthread', "-lrt'"]
