[xsd-users] Make suitable dependency generation

That was actually intentional. Normally, make rules specify targets
without the directory parts and if they are residing in directories
other than the current directory, then they are located with the
help of VPATH. See, for example, Paul's Third Rule of Makefiles[1]
and How Not to Use VPATH[2].

But now, thinking about it some more, I believe we should include the
directory part since the makefile that is compiling the schema and that
specifies the output directory is most likely also the same makefile
that includes the generated dependency file. And if that dependency
file doesn't have the output directory part, then the dependency
information will be useless.

So I am going to make the change.

Also note that you can easily change this behavior even now with the 
--dep-target option, for example:

xsd --output-dir foo --dep-target "foo/bar.hxx foo/bar.cxx foo/bar.d" bar.xsd

A bit verbose but doable.
