dev-cpp/cpprestsdk: fix building with boost-1.89

The previous patching for building with boost-1.89 was insufficient.
This patches cmake files for finding boost removing all references to
the removed system stub. Also deadline_timer is no longer included by
the upstream includes in one of the http client cpp-files.
Deadline_timer is deprecated as well so opted for replacing it with
steady_timer instead. See upstream PR.
