dbuild: pass --tty when running in interactive mode

podman does not allocate a tty by default, so without `-t` or `--tty`,
one cannot use a functional terminal when interacting with the
container. that what one can expect when running `dbuild -i --`, and
we are greeted with :

```
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
```

after this change, one can enjoy the good-old terminal as usual
after being dropped to the container provided by `dbuild -i --`.
