tools/xenstore/xenstored_control.c: correctly print time_t

On 32 bit systems with 64 bit time_t (hello, Y2038 problem),
the following error occurs otherwise:

| xenstored_control.c: In function 'lu_reject_reason':
| xenstored_control.c:646:70: error: format '%ld' expects argument of type 'long int', but argument 5 has type 'time_t' {aka 'long long int'} [-Werror=format=]
