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]
