Dependencies Builder: disable LINKSTATIC for OIIO

It'll likely give issues with system boost libraries in ubuntu/debian due
to this distros doesn't like static linking and not building static libs
with -fPIC flag.

Disabling LINKSTATIC should be quite painless since blender requires the
same image libraries as oiio does.
