Apply patch #76254 from Roman I Khimov about lensfun interface which don't mangle cropFactor if it's set. This behaviour was introduced by polish commit bebef401. With this branch present we always get cropFactor of -1.0 in LensFunFilter::filterImage() and given that lensfun library just uses crop factor of 1 which leads to obviously wrong calculations for cropped cameras.
