offscreen: always create a valid QPlatformIntegration 

Commit f4a66e5c accidentally made it so that the offscreen
plugin would produce a null QPlatformIntegration on
X11 if QT_QPA_OFFSCREEN_NO_GLX is set.

Restore previous logic where the generic QOffscreenIntegration
is created if the X11 code path did not create an object.
