mksandbox --without-xsrc option

[Simon Burge <simonb%NetBSD.org@localhost>]

Hi folks,

The below patch adds a --without-xsrc option similar to the existing
--without-src option.  I've been using this to build a sandbox for a
couple of pkgsrc quarterly releases now without any problems.

Any reason not to commit this?

Cheers,
Simon.
