[Libguestfs] [libguestfs-common PATCH 1/2] detect_kernels: tighten "try" scope

We want to catch Not_found from (our own implementation of) "List.find_map". There's no need (and it makes no sense) to push the "prefix_len" calculation down into the "try" scope. Keep the "try" scope as narrow as possible.
