progress_cb: avoid buffer overflow
The progress bar output function would blindly use the terminal width
without bounds checking. When using a very wide terminal that caused a
buffer overflow and segfault.
We now limit the max bar with to 255 columns, and I simplified the code
to avoid an extra snprintf and buffer.
