Convert parser of struct itimerval to new mpers infrastructure

* defs.h [ALPHA] (print_itimerval32): New prototype.
* print_time.c (print_itimerval): New mpers printer.
[ALPHA] (timeval32_t): New typedef.
[ALPHA] (print_timeval32_t, print_itimerval32): New functions.
* time.c (sys_getitimer, sys_setitimer): Use print_itimerval instead
of printitv.
[ALPHA] (sys_osf_getitimer, sys_osf_setitimer): Use print_itimerval32
instead of printitv_bitness.
(tprint_timeval32, tprint_timeval, printitv_bitness, printitv): Remove.
