fix crash when using GTK 2.14 function in old gtk
This is additional fix for bug 23569.
Previous fix (SHA1 7fcf1cf674d09d9dd1d41e2913252017f1d599ca) is not enough.
QGtkStyle was still crashing with old gtk (< 2.14)
in drawComplexControl () function.
Bug was reproducible on CentOS 5.x and Red Hat 5.x.
Current patch makes the same check as in commit mentioned but in another
line of code.
