[PATCH 1/6] t/www_static: modernize test

[Eric Wong <e@80x24.org>]

autodie is standard in Perl v5.10+ and we now have
PublicInbox::IO::write_file to denoise test setup code.
Then we'll favor the non-wantarray calls to tmpdir() and
rely on an overloaded stringification rather than keeping
the $for_destroy object around.
