gnutime: update to 1.9

1.8 -> 1.9:
- reports percent CPU usage for programs lasting less then 1 second.
- previously, time would report '??%' if programs lasted less than 1
  second.
- "time -p" no longers adds the "Command exited with non-zero \ 
status"
  message.

1.7.1 -> 1.8:
- First official release under GPLv3-or-later.
- support new -q/--quiet option to suppresses abnormal
  program terminal (non-exit codes or signals).
- now uses the following exit codes (same as GNU coreutils' env):
   125 = Wrong usage or internal error prior to exec attempt.
   126 = Program located, but not usable.
   127 = Could not find program to exec.
- now exits with code '128 + Signal number' when the program
  is terminated by a signal.

- time now reports MAX-RSS values correctly on modern systems
  (the old code base, last updated in 1996, incorrectly calculated
  pages/kilobytes and overestimated MAX-RSS).
- Use gnulib modules and build infrastructure.
- New tests infrastructure (make check).
- Portability improvements (e.g. detection of time.h, sys/resources.h,
  getrusage now delegated to gnulib).

1.7 -> 1.7.1:
- Released under GPL V3 License
