build: Use `syn` to pick out constants #49

As #48 has shown, picking flags out of the bindgen output is relatively brittle. It worked well for as long as we were only checking for some string's presence, but for CONFIG_ things we need a bit more.

This just uses the syn parser to parse the source code; that's a well established tool that's also used in proc macros.

Leaving this as a draft for a while to gather input and think more about it, but so far I like it.

Merged after it still builds well with current master and some RIOT/Rust versions in.
