[OE-core] [OE-Core][PATCH v2] openssh: Add dependency on ssh for sftp

[Alex Kiernan]

Add missing dependency on the ssh binary for the sftp client to avoid
failure at runtime if it's not been installed through another dependency
chain.

This introduces a note if PREFERRED_RPROVIDER_ssh is not set and it
can be satisfied by multiple providers (e.g. openssh and dropbear).

Changes in v2:
- Depend on ssh not ${PN}-ssh so it can be satisfied by openssh or dropbear
