Fix bind-mount to manila's bootstrap container

When deploying with tls-everywhere, there are
more connection options necessary for the Overcloud
manila database bootstrap container to connect
to mysql. These connection options are present in
the configuration folder
/var/lib/config-data/manila/etc/my.cnf.d/tripleo.cnf.

Fix the bind-mounts on the manila_api_db_sync
container so it doesn't fail to find this
configuration.
