Jakob Unterwurzacher 03bf604fc0 syscallcompat: OpenNofollow: use O_DIRECTORY flag 
...when opening intermedia directories to give us an
extra layer of safety.

From the FreeBSD man page:

     This flag can be used to prevent applications with elevated
     privileges from opening files which are even unsafe to open with O_RDONLY,
     such as device nodes.
