The Ed25519 key pairs are much shorter than RSA pairs and are supported

SSH keys, many suggest using Ed25519 rather than RSA, however consider
the former as not yet widely established. OpenWrt likely has a positive
influence on that development.
As enabling Ed25519 is a compile time option, it is currently not
possible to install the feature via `opkg` nor select that option in an
Due to the size impact the option should only be enabled for devices
This approach seems cleaner than splitting `dropbear` into two packages
like `dropbear` and `dropbear-ed25519`.
