Map text purposes to Wayland content purposes

The Wayland backend passed yasl's purpose values straight to
set_content_type. The values differ: yasl TERMINAL (3) reached the
compositor as the protocol's NUMBER. Map each yasl purpose to its
protocol constant. Unknown values fall back to normal text.
