journal: when copying journal file to undo NOCOW flag, go via fd
We have the journal file open already, hence reference it via the fd
insted of the file name. After all, some other tool might have
renamed/deleted it already.
Let's not actually reuse the fd though, since we want a separate file
offset for the copying, hence just make it simply and reopen via
/proc/self/fd/.
