opencv: fill in missing FastCV gaps

Browse Source 
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.
