HTTP::Cookies destructor

Thanks for patching HTML::Parser.

I've found another patch, from around the same time, that I sent to you
and isn't in the latest release.  This is for HTTP::Cookies, in the LWP
distribution.  The destructor for HTTP::Cookies can clobber $! and the
other global status variables.  Destructors need to avoid this because
they are called implicitly.  This patch fixes it:
