Bug#880438: libopencv-core-dev: installs headers in opencv2 directory

[Simon Frei]

I just stumbled upon these two different dir names when upgrading to
opencv3 and assumed this was controlled by debian packaging and has been
an oversight in the transition. The digikam compiling issue was resolved
on the spot back then. This report can be closed - thanks for your
explanation and sorry for wasting your time.
