When OpenCV is being built with the "fastcv" packageconfig, several
OpenCV libs are linked against the libfastcv.a. At runtime this lib will
dlopen(libfastcvopt.so.1), providing a fallback to slow algorithms, etc.
However as it is dlopen() rather than dynamic linking, there is no
runtime dependency.

In Yocto, if we enable a feature, we expect that all runtime
dependencies are pulled in. Utilize the qcom-fastcv-binaries recipe
provided by the meta-qcom layer and pull in libfastcvopt1 package as
required.
