ntdll: add a warning about running wine as root (try 3)

[Austin English]

Been seeing it quite a bit recently in the forums. While the patches
to break using sudo/su have helped a bit, seems some users are
convinced they need to run wine as root. This adds a non fatal
message, so no functionality is lost for those that _do_ need to run
as root.

Try 2:
Made warning a bit more verbose. Changed geteuid to getuid, since we
already check for that function, and geteuid is a bit is superfluous,
since sudo should already be prevented.

Try 3:
Clean patch that applies to git master.
