Subject: [PATCH] ssh_filter_btrbk: update ssh_filter_btrbk.sh to use readlink

bugfix for: 796b6bd9bf70d95e799e5b084088001db9d487ef

Replace realpath with readlink in allowed commands. Commit 796b6bd substituted readlink for realpath in file "btrbk"; this commit propagates the change to ssh_filter_btrbk.sh.
