Missing include in simple_run.c

[Rainer Jung]

When compiling trunk, I get

simple_run.c:242: warning: implicit declaration of function 
'ap_run_drop_privileges'

I can fix it with the following patch:

 #include "ap_listen.h"
 #include "mpm.h"
+#include "mpm_common.h"

 /**
  * Create Timers.

I'm not sure though, whether that's the best way, or you want to move 
the symbol to another include file instead.
