Modernize PBAP phonebook-ebook plugin for newer libebook version
of the Evolution Data Server.

The ebook plugin was introduced during GSoC 2011 [1] and allows
BlueZ to share contacts stored in the Evolution Data Server to
connected clients such as car multimedia systems.
With the rise of Mobile Linux thanks to the PinePhone and Librem 5,
this plugin was modernized to compile with newer libebook versions
because the API was changed [2].
