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.
