[librsvg] Remove a bunch of unused rsvg_path_builder_*() functions

[Federico Mena Quintero <federico src gnome org>]

commit 702d7c048556c484b1ecf14a0e2d28a69f326862
Author: Federico Mena Quintero <federico gnome org>
Date:   Wed Apr 26 16:12:56 2017 -0500

    Remove a bunch of unused rsvg_path_builder_*() functions
    
    All the callers are now in shapes.rs, so the functions exported from
    RsvgPathBuilder to C can be removed now.
    
    Also, remove rsvg_path_parser_from_str_into_builder() from the Rust
    code; it's also unused.
