Stop using non-standard %Zu and %Zd formats for size_t printing

The documented formats are %zu and %zd, but since our (normally disabled)
"fast" printf code doesn't support those too, I convert them to %lu and %ld.

* bjm.c (sys_query_module): Convert %Zd usages to %lu.
* system.c (sys_sysctl): Likewise.
