Replace strncpy with memcpy 

since the length of data to 
be copied has already been determined with strlen(). Replace strncpy()
with memcpy() to address the warning and optimize the code a little.

| ippool_config.c:112:2: note: 'snprintf' output between 8 and 55 bytes into a destination of size 48
|   112 |  snprintf(prompt, sizeof(prompt), "ippool-%s", server_name);
