fix: correct start of data container

[igolman]

Description

Following the update to recent image PR 330 the data container won't start due to deprecation of UsePrivilegeSeparation option:

This release includes a number of changes that may affect existing
configurations:

 * This release deprecates the sshd_config UsePrivilegeSeparation
   option, thereby making privilege separation mandatory. Privilege
   separation has been on by default for almost 15 years and
   sandboxing has been on by default for almost the last five.

$ docker logs -f e279d5a7c6ae
command-line line 0: Deprecated option UsePrivilegeSeparation
Missing privilege separation directory: /run/sshd
