media-libs/opencv: various fixes
- Explicitly depends on virtual/lapacke to prevent its cmake build scripts from
implicitly disabling lapack support when it can't find lapacke.h.
- Link with cblas when sci-libs/lapack is supplimented as the default lapack
implementation.
- examples USE requires contribdnn USE to be enabled to prevent build failure.
