library: Adjust version for release

library: Adjust version for release

Previous release incremented the age instead of incrementing the
revision. The age can only increment if revision (internal changes
only) or current (API changes) also increments.

A C:R:A of 8.0.2 means its the latest revision of 8.0 library and
any binary linked against 8.0 will work. This is our third revision
of the 8.0 library.
