test_string.rb: enable huge test only on possible platforms

* test/ruby/test_string.rb (test_LSHIFT_neary_long_max): enable
  only on platforms where string size range is smaller than memory

  time on other platforms, as it is hardly possible that a string
  size becomes neary LONG_MAX if long size equals pointer size.
