evas gl: Check EGL version before using dlsym
A recent commit broke texture_from_pixmap for NVIDIA EGL (again), because eglCreateImage is a symbol in but isn't in fact implemented by the driver. That's because eglCreateImage() is exposed by libglvnd but the underlying EGL implementation is NVIDIA and its version is only 1.4, not 1.5 (where the API was introduced as core). Instead of reverting the patch, it's better to cover our bases properly and use dlsym() only if the version is right. Note that GetProcAddress() may return garbage function pointers for ALL functions as dynamic virtual functions may be created on the fly by libglvnd. So it is absolutely necessary to check the extension string as well. See 0255f14dc2189c71776408b00307b8488bfa4dc5
