bookmarks: create undo.bookmarks using repo.opener instead of util.copyfile
This more closely matches how the other undo files are created, and we
don't care about settings permissions or times on the file, which can
fail if the user running hg doesn't own the file.
archival: don't set gzip filename header when there's no filename
This mainly affects hgweb, which can generate tar.gz archives without
filenames. Without this change, the header would be set to ".gz",
which can confuse Safari into extracting the file and renaming it to
"gz" when "Open 'safe' files after downloading" is enabled.
