[Buildroot] [PATCH v5] package: add opencv

[Samuel Martin <s.martin49@gmail.com>]

OpenCV is a free, open-source, cross-platform computer vision library

Changelog:
 v1: initial submission
 v2: changes according to Thomas Petazonni's review:
     - remove obvious unneeded options
     - typo and style fixes
     - do not use 3RDPARTY_LIBS
 v3: changes according to Thomas Petazonni's review:
     - typo and style fixes
     - remove host package (not needed)
 v4: update CMAKETARGET call to follow the infra.
 v5: - add post install hooks (following Mike Davies' remarks):
       - do not install doc
       - do not install OpenCVConfig.cmake in the target
     - optionally install data in the target
     - remove the 'Build examples' option (only install source files)
     - disable precompiled header usage (automacally disabled when
       compiler size optimization is set)
