FS#3216 - Enable by default ed25519 on dropbear


As of latest master OpenWRT still does not enable ed25519 by default in dropbear.
ed25519 is becoming fairly widespread and is even the current default key exchange algorithm in OpenSSH.
As per adding this feature would only add around 8KB to the build size of dropbear max
and as per your build files 12KB in MIPS.
I believe 10Kb is relatively negligible, even for routers, and as such I don’t really see
any reason to have it disabled by default, especially when something as
crucial as public key ssh gets broken otherwise without any warning, leading to a horrendous UX.

Would you be so kind as to think about changing the default?
