egl: set preserved behavior for surface only if config supports it

egl: set preserved behavior for surface only if config supports it

surface when client queries surface attributes. As example, configs
for DRI3 do not support preserved behavior but here we were setting
preserved behavior for pixmap and pbuffer.
