Fixes to syborg-graphicswrapper.vcproj
These changes allow syborg-graphicswrapper to link against the hostthreadadapter and khronosapiwrapper libraries built by the graphics.simulator component.
The .vcproj file uses relative paths, which requires that the following three packages are laid out as follows:
os/
graphics
adapt/
graphics.simulator
qemu
@rem Used by the buildbot "compile" step.
