main/openssh: Place libcrypto dependency on openssh-client-common instead of openssh.

@psykose 4b0ca951 resolved #14718 (closed) for apk add openssh, but it's still possible to run into OpenSSL version mismatch. Built against 30100000, you have 30000080 by installing openssh-client (or openssh-client-common, etc). You can see this in action at https://gitlab.alpinelinux.org/dHannasch/openssl-version-mismatch/-/jobs/996415.
