[winswitch] Xpra 2.3.2 - CentOS 7 packaging conflicts

[Antonio Trande]

I'm seeing that xpra-2.3.2 cannot be built on CentOS7 because of a
compiling error:

Error compiling Cython file:
------------------------------------------------------------
...
    cdef const void *get_mem(self):
        return self.p
    def __getbuffer__(self, Py_buffer *view, int flags):
        PyBuffer_FillInfo(view, self, <void *>self.p, self.l, 1, flags)
                        ^
------------------------------------------------------------
xpra/buffers/membuf.pyx:84:25: Call with wrong number of arguments
(expected 5, got 6)

Build log:
https://kojipkgs.fedoraproject.org//work/tasks/5031/28035031/build.log

If everything goes fine, i can include xpra in EPEL7 repository too.
