Rename GetRsaPrivateKeyPath to GetECDSAPrivateKeyPath for backward co…

…mpatibility

We were using RSA Algo long time ago and this function is used to
provide a backward compatibility for that version of crc but since in
previous commit we have updated the ssh algo from ecdsa to ed25519, to
have the backward compatibility for some released version we are
renaming this function.
