Remove 15 libraries from OCC_LIBS_COMMON that KiCad never
links against: persistence format libs (TKBin*, TKXml*,
TKTObj), unused modeling algorithms (TKFeat, TKFillet,
TKOffset, TKXMesh), and OCCT viewer internals (TKMeshVS,
TKOpenGl). This reduces the common set from 35 to 22.
In loadmodel.cpp, drop the unused AIS_Shape.hxx include and
add an explicit Quantity_ColorRGBA.hxx include that was
previously pulled in transitively through AIS_Shape.
Add /usr/opencascade to the Unix library search hints.
