Invalid rerun dependency path in build.rs

[crumblingstatue]

Here:

println!("cargo:rerun-if-changed=in/*");

Globs are not expanded by Cargo, they are interpreted literally, meaning this is likely referring to a nonexistent location.

Ref rust-lang/cargo#4076

This results in constant recompiling down the dependency chain: error_chain (which depends on backtrace which depends on cpp_demangle), which is extremely annoying.

Thanks for catching this! Fix on the way.
