Fix transformation in eglfs backingstore
While not visible with forced-fullscreen windows, the formula
used to set up positioning on the Y axis is wrong. (with the GL
coordinate system Y goes 1..-1 when moving top-to-bottom)
Taken from kms' version of the backingstore which had the formulas
corrected.
