meson: Use meson's convention
The convention when naming dependencies is to use the '_dep' suffix, which helps detecting dependency variables. The variables have been renamed to follow this convention. The dependencies that are also used once, are declared in the target's dependency array which helps meson processing less and also one less variable is needed. https://bugzilla.gnome.org/show_bug.cgi?id=791421
