src/pacman/query.c: do not exit -Qo with error if file does not exist
Query operations act on the local db, not the filesystem. Also, a valid use case for -Qo is to discover what package owns a deleted file so it can be reinstalled. Closes FS#55856. Signed-off-by: Ivy Foster <iff@escondida.tk> Signed-off-by: Allan McRae <allan@archlinux.org>
