splice: update mtime and atime on files
Splice should update the modification and access times on regular files just like read and write. Not updating mtime will confuse backup tools, etc... This patch only adds the time updates for regular files. For pipes and other special files that splice touches the need for updating the times is less clear. Let's discuss and fix that separately.
