libusb_util.c: Avoid gcc warning about strncpy()

What we're doing is actually legal: We copy the full size of the
destination array, and then overwrite the last byte with NUL.  However,
gcc isn't smart enough to see that:

libusb_util.c:162:5: warning: ‘strncpy’ specified bound 20 equals destination size [-Wstringop-truncation]
     strncpy(out[out_idx].path, path, sizeof(out[out_idx].path));
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let's copy one byte less to make it happy.
