[PATCH (resend)] ui-stats.c: fix warning on 32-bit

[Eric Wong]

gcc 6.3.0-18 on Debian oldstable emits the following warning,
despite uintptr_t and "unsigned long" having the same size:

> ../ui-stats.c: In function ‘print_authors’:
> ../ui-stats.c:340:18: warning: format ‘%lu’ expects argument of type ‘long 
> unsigned int’, but argument 2 has type ‘unsigned int’ [-Wformat=]
>      htmlf("<td>%lu</td>", (uintptr_t)date->util);
>                   ^
