That's the wrong question to be asking. Outputting a backspace
character will not (at least not reliably) erase that newline from the
output. If you really want to get rid of that \n, even though it
already sits in the file, your only choice is to re-open the file in
write/append mode, truncate it to one character less than its original
length, and re-open it again for writing.

In the light of that, I'd strongly suggest forgetting about the whole
plan, unless there's strict necessity to do it (order from your boss,
or something).
