gzip does not set uid and gid anymore (because of pledge)

[Remi Locherer]

Hi

After upgrading a firewall to 5.9 I noticed that the ownership of logfiles
is not as I specified in newsyslog.conf. After newsyslog compressed the files
the ownership is always root:wheel.

I figured out that this is because gzip can not chown anymore since it was
pledged. The below patch fixes this.
