[1/2] wcmd/setshow_attrib: Moved from internal to external attrib.exe

[Dan Kegel]

Welcome to wine development!

Problems with your patch:
- you forgot to add your test to rsrc.rc
- you forgot to include an expected output file
- don't change .h files in patches that don't need the changes

Please submit just the tests first, make sure 'make test' runs
your tests, and make sure the .exe produced by 'make crosstest'
passes on winetestbot.

You might want to send the next patch to me for review before
posting to wine-patches; you'll probably run into several
more gotchas that it'd be nice to have cleared up before
you post again.
