add.c: drop newline in permission log message
This is the only log message produced by pacman that includes an embedded newline, and it looks very incongruous in a typical pacman.log.
I tried to propagate this change into the various translations of the message. Most were straightforward, but a few languages have an alternative comma character, which I tried to match, and some translators are ahead of the curve and have already chosen to elide the newline. I left those translations alone.
