opencv 4.x: some contrib modules require eigen library

[db4]

Specify library name and version: opencv/4.x

Combination of with_contrib=True and with_eigen=False makes find_package(OpenCV) fail with

-- Conan: Target declared 'opencv::opencv'
CMake Error at build/generators/cmakedeps_macros.cmake:39 (message):
  Library 'opencv_alphamat453' not found in package.  If
  'opencv_alphamat453' is a system library, declare it with
  'cpp_info.system_libs' property

contrib_sfm also requires with_eigen, so I added a check to validate()
