[Buildroot] [PATCH 1/1] package/zxing-cpp: drop opencv and qt dependencies

[Fabrice Fontaine]

opencv and qt handling can be dropped since switch to an active fork in
commit 456a7398316655ad0b669635f580e4887c24a700 as they are only used
when examples are enabled resulting in the following warning:

CMake Warning:
  Manually-specified variables were not used by the project:

    BUILD_DOC
    BUILD_DOCS
    BUILD_EXAMPLE
    BUILD_TEST
    BUILD_TESTING
    BUILD_TESTS
    CMAKE_DISABLE_FIND_PACKAGE_OpenCV
    CMAKE_DISABLE_FIND_PACKAGE_Qt5

While at it, also drop BUILD_EXAMPLES which is already passed by
pkg-cmake.mk

Fixes: 456a7398316655ad0b669635f580e4887c24a700
