    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.
