patch 5 for dazukofs release 3.0.0

This patch is not a bug fix, but useful to increase performance:

dazukofs reports open events for all kind of files. But this does
mainly make sense for regular files (who wants to check
fifos for malware?).
Thus a simple check ensures that only open events for regular
files are announced to userspace.

(On my system a simple "find" command executed in /usr which was
mounted with dazukofs resulted in over 90000 context switches -
only caused by opening directories..)
