[PATCH] use "git init-db" in tests

Unless there was a special reason to use git-init-db from $PATH, could the patch below be accepted? It makes the test suite use git-init-db from the "the binaries we have just built".

The reason, why we need the patch even if the $PATH is set, will be better explained by glibc's sources: the lookup does not stop if the file exists but has no execute permission.

See file posix/execvp.c, the loop iterating over elements in $PATH:

          switch (errno)
            {
            case EACCES:
              /* Record the we got a `Permission denied' error.  If we end
                 up finding no executable we can use, we want to diagnose
                 that we did find one but were denied access.  */
              got_eacces = true;
                 ...
              break;
            ...
            }
      ...
      /* We tried every element and none of them worked.  */
      if (got_eacces)
        /* At least one failure was due to permissions, so report that
           error.  */
        __set_errno (EACCES);

 By the same reason, the whole testsuite should be reviewed to use 
 "git <command>" notation.
