factor out time_t-to-string conversion idiom

* src/system.h: Include "inttostr.h".
(timetostr): New function, factored out of...
* src/date.c (show_date): Use timetostr.
* src/du.c (show_date): Likewise.
* src/ls.c (print_long_format): Likewise.
* src/pinky.c (time_string): Likewise.
* src/stat.c (human_time): Likewise.
* src/*.c: Don't include inttostr.h, since system.h does.
* src/c99-to-c89.diff: Adjust offsets.
