build: Build with -Wno-duplicated-branches if the compiler supports it
Otherwise building with gcc 7 fails like this:
_dbus_bindings/server.c: In function ‘DBusPyServer_set_auth_mechanisms’:
/usr/include/python2.7/abstract.h:1161:43: error: this condition has identical branches [-Werror=duplicated-branches]
(PyList_Check(o) ? PyList_GET_SIZE(o) : PyTuple_GET_SIZE(o))
^
_dbus_bindings/server.c:101:14: note: in expansion of macro ‘PySequence_Fast_GET_SIZE’
length = PySequence_Fast_GET_SIZE(fast_seq);
