conntrack: fix compiler warnings

.... those do not indicate bugs, but they are distracting.

'exp_filter_add' at filter.c:513:2:
__builtin_strncpy specified bound 16 equals destination size [-Wstringop-truncation]

This warning is because the size argument passed to strncpy() is
identical to buffer size, i.e. if hit the resulting string is not
0-terminated.

read_config_yy.y:1625: warning: '__builtin_snprintf' output may be truncated before the last format character [-Wformat-truncation=]

  124 |         snprintf(conf.logfile, FILENAME_MAXLEN, "%s", $2);

... its because the _MAXLEN constants are one less than the output
buffer size, i.e. could use either .._MAXLEN + 1 or sizeof, this uses
sizeof().
