Cast the getpid() return value and adapt the format string.
Avoids the following warning:
CC simpletrace.o
/Data/QEMU/qemu/simpletrace.c: In function 'st_set_trace_file':
/Data/QEMU/qemu/simpletrace.c:77: warning: format '%u' expects type 'unsigned
int', but argument 3 has type 'pid_t'
v2:
* Don't use %lu for getpid() on Haiku since on x86_64 it returns an int.
Always cast to long (largest allowed pid_t type) and use %ld instead.
Suggested by Ingo Weinhold.
