enhance sort order conformance test to test for consistent ordering, but not a specific locale

Or just to the (unwritten) implementation guidance doc?

At today's meeting we have come to the conclusion that we should default to C for now

[mr-c]

new plan:

1. No more default locale.
2. Duplicate https://github.com/common-workflow-language/common-workflow-language/blob/master/v1.0/v1.0/glob_test.cwl with a different "wrong" order
3. Add step to compare of glob_test.cwl and glob_test2.cwl, fail if not matching
4. Document in v1.1 v1.2.1 that glob sort orders must be consistent.

Also confirm that when an array of patterns is passed to glob that each result is sorted, but not all together. Thanks to @milos-ljubinkovic for finding this!

Hi.

The reason why I opened common-workflow-language/common-workflow-language#801 is that the behavior of glob with array is not documented and that the actual behavior in cwltool (that passes both of 121 and 172) seems to be inconsistent for me.
If the behavior is documented in the spec, it is OK for me.

@tetron @mvdbeek @GlassOfWhiskey and I affirmed the plan in #233 (comment) today

@GlassOfWhiskey reminded us that cwltest might need an upgrade to ignore the order of arrays..
