cygport: Request a new feature in order to set owner/group names in packaged tarballs.

[Lemures Lemniscati <lemures.lemniscati@gmail.com>]

Hi!

This is another patch, so that cygport shall make tarballs with
specified owner and group names.

e.g.) Invoke like this:

PKG_OWNER_GROUP=lovely/cygwin cygport fabulous.cygport package

and we'll get tarballs with a owner name 'lovely' and a group name 'cygwin'.

But, there may be more suitable names for variables other than
PKG_OWNER_GROUP, PKG_OWNER, PKG_GROUP...

Regards,

Lem
