Victor Toso fcf9a53595 examples: Fix format-truncation on debug
As description is used only for debug, we can extend it to be sure to
fit 256 from string variable plus 3 chars from " - " as described in
gcc warning below

 | testlibusb.c: In function ‘print_device.constprop’:
 | testlibusb.c:188:51: warning: ‘ - ’ directive output may be truncated writing 3 bytes into a region of size between 1 and 256 [-Wformat-truncation=]
 |      snprintf(description, sizeof(description), "%s - ", string);
 |                                                    ^~~
 | testlibusb.c:188:5: note: ‘snprintf’ output between 4 and 259 bytes into a destination of size 256
 |      snprintf(description, sizeof(description), "%s - ", string);
 |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Closes #460
