libps: fix task/thread times fetching

Introduce PSTAT_TIMES to force the retrieval of both PSTAT_TASK_BASIC
and PSTAT_THREAD_BASIC. Task basic info contain the user and system
times of terminated threads which the code wrongly assumes is always
present along with process info.

* libps/procstat.c (add_preconditions): Set both PSTAT_TASK_BASIC and
PSTAT_THREAD_BASIC as preconditions for PSTAT_TIMES.
(summarize_thread_basic_info): Add terminated threads times only if
task basic info are available.
(set_procinfo_flags): Provide summarize_thread_basic_info with flags of
available info.
(proc_stat_set_flags): Set PSTAT_TIMES as available if it was needed and
any of PSTAT_TASK_BASIC or PSTAT_THREAD_BASIC could be fetched.
* libps/ps.h (PSTAT_TIMES): New macro.
* libps/spec.c (ps_get_usr_time): Indicate the getter needs PSTAT_TIMES
instead of PSTAT_THREAD_BASIC.
(ps_sys_time_getter): Likewise.
(ps_tot_time_getter): Likewise.
