Clean up the script so that any unexpected error terminates the script, and stop suppressing errors that may contain useful information (for example, that you are using the stable version but need to use the nightly). This is useful because if hyper.h is not up to date going forward the CI should flag it. As is, there are a bunch of changes to hyper.h that have not been checked in (or were generated by a newer version of the cbindgen script.) Fixes #2483.
