Synchronize RPM and pkg-config versions

Synchronize RPM and pkg-config versions

This change also introduces CYNARA_VERSION cmake variable which will need
to be kept in sync with rpm package version.
We cannot rely on passing version from RPM spec since we want to be able
to build Cynara independently of the Tizen build system.
