Subject: [PATCH] Remove pointless exports from ssh/rc, add process-model
 comment

ssh/rc runs as a sshd child process so exports never reach the user's
shell. SSH_REMOTE_AUTH_SOCK was set and exported but never used (a
leftover from a prior failed fix attempt). SSH_AUTH_SOCK was reassigned
to the symlink path and exported, also to no effect. Remove both.
