John Cupitt 78acd9b7a0 use a better name for the dzsave temp dir
see https://github.com/jcupitt/libvips/issues/242

dzsave with deepzoom layout and fs container writes a temp dir called
dzsave-temp-324857 or similar, and makes sure that this directory does
not exist

after write, the foo_files and foo.dzi files are picked out to the
current dir and the temp removed
