This upgrades pgzip to include a fix to prevent negative byte counts being returned from pgzip.Write, which cause panics in bufio.

These panics manifest when using compressed xtrabackup backups as:

Error: <_Rendezvous of RPC that terminated with (StatusCode.UNKNOWN, caught panic during Backup: bufio: writer returned negative count from Write)>
