Bug#867067: create directory for nfsdcltrack

[Hieu Luu]

Hello Stephen,

I was able to resolve this by following these steps (after doing strace 
nfsdcltrack init to find out why it returned -13) **[1]**

1. `# mkdir /var/lib/nfs/nfsdcltrack`
2. `# nfsdcltrack init`
3. check if file `/var/lib/nfs/nfsdcltrack/main.sqlite` is present
4. check with `sqlite /var/lib/nfs/nfsdcltrack/main.sqlite`
 * querying `.tables` gives `clients` and `parameters`
 * querying `.schema clients` gives `CREATE TABLE clients (id BLOB 
PRIMARY KEY, time INTEGER, has_session INTEGER);`
 * querying `.schema parameters` gives `CREATE TABLE parameters (key 
TEXT PRIMARY KEY, value TEXT);`
5. `# systemctl restart nfs-server`

Your `journalctl` should show success message.

**[1]** strace output (clipped)
