Subject: [PATCH 108/112] Fix string truncation issues detected by GCC 8
This fixes string truncation warning generated by GCC of the form:
irqbalance.c:485:2: warning: 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation]
strncpy(addr.sun_path, socket_name, strlen(socket_name));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Using source size in strncpy so fix that by using destination size.
For the instance of this issue in irqbalance-ui.c, fix the issue by
eliminating the unneeded temporary buffer.
