rhel: Avoid creating an empty database file.

In 59e8cb8 ("rhel: Move conf.db to /var/lib/openvswitch, using symlinks.")
conf.db is created as empty file in /var/lib/openvswitch, if it doesn't
exists, but this prevent ovsdb-server to start.

This commit changes the previous behaviour to set
/var/lib/openvswitch owner to openvswitch:hugetlbfs, if built with
dpdk, or openvswitch:openvswitch.

Fixes: 59e8cb8 ("rhel: Move conf.db to /var/lib/openvswitch, using symlinks.")
