Bug 28430

Mtree does not correctly compare files against their specs if
one of the files has flags such as nodump set.  The files not
having the flags set show errors like the following:

za:     flags ("nodump" is not "none")
za/z:   flags ("nodump" is not "none")
za/z/a: flags ("nodump" is not "none")

Fix: 

The patch below on spec.c corrects the problem.  The patch
on create.c is a patch to what looks like another bug.  It
is unclear what the bug does.
