[LLDB] [test] Allow differing order of some matches

[mstorsjo]

Summary

These can appear in a different order depending on the relative layout of the source and build trees.

I would prefer if we could have a deterministic order in the list of files when dumping them (e.g. sorting by name), but I'm fine with landing this because this test is failing on all of my machines. I'll file a radar for Jonas so that this will actually be properly fixed at some point. Thanks for looking into this!
