unbound: remove references to compile-time dependencies in outputs

Browse source 
Previously unbound dev dependencies would leak into the unbound binary
through the embedded configure flags string in the binary.

Before this commit `unbound -V` would list something like this:

> Version 1.13.1

Notice: All the paths are now invalid and thus do not produce a
reference in the output binaries.

This removes a total of 2MiB from the closure of unbound.
