Complete a bit more IoCreateFile tests, taking into account relatives.

A side note (related to first commit - actually to these test as a whole):
It's pretty unfortunate that they work (on my Windows 2K3). They just expose
a totally different behavior than expected reading R. Nagar (pp 478 - 479).
The experimental behavior also being different from behavior expected from IFS
samples provided by MS.
Perhaps some magic in the callpath between IopParseDevice return and IoCreateFile return?
