PictureLayerImpl: Use ceil() instead of ceilf()

ceilf() is only formally mentioned in C++17, even though previous versions
of the standard say <cmath> should have the same contents as C's math.h.

libstdc++ does not ship ceilf() in its cmath, but the ceil(float) overload
that _is_ in the standard is available everywhere, so use that instead.

This fixes the build with libstdc++ after 77b67445ba ("Elements with fixed
bottom and top stick to top"):

    ../../cc/layers/picture_layer_impl.cc: In member function ‘void cc::PictureLayerImpl::UpdateViewportRectForTilePriorityInContentSpace()’:
    ../../cc/layers/picture_layer_impl.cc:738:16: error: ‘ceilf’ is not a member of ‘std’
               std::ceilf(-total_controls_height * hidden_ratio));  // bottom
                    ^~~~~
    ../../cc/layers/picture_layer_impl.cc:738:16: note: suggested alternative: ‘ceil’
               std::ceilf(-total_controls_height * hidden_ratio));  // bottom
                    ^~~~~
                    ceil
