Version vendor libprotobuf-cpp-* libraries

Vendor prebuilts reference the protobuf runtime libraries, but the
runtime libraries do not have a stable ABI.  Add a version suffix
to the names of the libraries when used by vendor modules so that
old versions can be left in place when the protobuf version is
updated.

Also adds a test that verifies that the library names match the
version number to ensure the version number gets updated when
protobuf is updated.
