libgui: Add pre-MR2-compatible symbol for setPosition

SurfaceControl::setPosition now takes floats instead of integers as
arguments, which breaks linkability from pre-MR2 blobs. Add a direct
compatibility wrapper, since the values are treated in the same
way.

Rework BOARD_EGL_NEEDS_LEGACY_FB implementation

The problem with the window format boils down to a circular
dependency that makes service startup hang, so skip a round of
queues-to-window-composer to avoid it but keep using regular
Surface objects as windows, instead of replacing them with
native windows.
