nobu 4756365503 dir.c: err at glob failure
* dir.c (glob_helper): raise a SystemCallError exception when
  opendir() failed, except for ENOENT, ENOTDIR, and EACCES.  this
  behavior predates 1.0; the comments in glob.c claimed that
  glob() returned -1 on error but actualy the pointer to a global
  variable, then dir_glob() did check only -1 as the comments, and
  ignored actual errors.  [ruby-core:80226] [Bug #13276]
