benchmark: use fallback gettime provided by Gnulib's timespec module

If CLOCK_PROCESS_CPUTIME_ID is not defined, a fallback gettime
function was defined as an inline function.  Given that "timespec.h"
from Gnulib already defines such a fallback function with the same
name, it's not necessary to redefine it.  This should fix the build
issue with Clang:

  In file included from ../../gnutls-3.8.1/src/cli.c:65:
  ../../gnutls-3.8.1/src/benchmark.h:38:20: error: static declaration of 'gettime' follows non-static declaration
  inline static void gettime(struct timespec *ts)
                     ^
  ../../gnutls-3.8.1/src/gl/timespec.h:93:6: note: previous declaration is here
  void gettime (struct timespec *) _GL_ARG_NONNULL ((1));
       ^
