Attention:
ssh -qn is ssh -q -n where -n inhibits reading from stdin - good for ssh -q -n remotehost remotecommand. But it must be ssh -q remotehost < file and ssh -q remotehost << heredoc and ssh -q remotehost <<< herestring because here you want it to read from stdin.
Also I suspect that in a normal here-document the backtick expression `uname -r`is already locally evaluated, so the local result will be passed to the remote host.
A workaround is <<-"EOFSSH" where the quotes should suppress the immediate evaluation of backtick-expressions and all kinds of $-expressions in the following here-document.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
NAME
ssh-keysign -- ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used.
SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)
HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
