protobuf: remove rdepends on abseil-cpp

That commit prefers sdk development instead of release images.
The additional libraries are not needed for protobuf at runtime.
Also any component depending on protobuf will have whole abseil-cpp in
sysroots so linking all the libraries is possible and any additional
ones will be installed.

What may not work is if protobuf is installed in sdk image and
application using it wants to use an additional abseil-cpp library.
However that is easily fixable by adding also abseil-cpp to sdk.
Removing hard-dependency in release images is much harder.
