sslh-main: fix config_lookup_int call

This func takes an int, not a long.  The current code triggers a warning:

sslh-main.c: In function 'config_parse':
sslh-main.c:275:5: warning: passing argument 3 of 'config_lookup_int' from incompatible pointer type [enabled by default]
     if (config_lookup_int(&config, "timeout", &timeout) == CONFIG_TRUE) {
                                               ^
