Flags any runtime_version < 1.0.0 as supporting old bytecode.

This would be paired with https://github.com/tessel/firmware/commit/1c47d42e89546127801e30249c744e44b7876111.

Colony with interpreter is given the `runtime_version` semver of v1.0.0. This is added to the version_info struct as a heuristic. This is used to determine if old Tessels support bytecode. Old versions lacking `runtime_version` (read: all) will use the default value of "true".

(No idea how this `runtime_version` will be updated, but probably not hardcoded.)
