C++: Fix build with nightly Rust

Cargo disallows dashes in library target names (lib.name in Cargo.toml), but when not set it uses the package name. That meant that dashes snuck in and rust-lang/cargo#12783 fixes that. The targets Corrosion creates correspond to the library name, so after that change it's slint_cpp. To make this work with stable cargo, explicitly switch lib.name to slint_cpp.
