[svn-r23917] Bug fix: HDFFV-8392
tools/h5diff/testh5diff.sh is run in every "make check", even after it
has passed in the previous run.
The error was in the previous change made to Makefile.am
when testh5diff.sh.in was created.  The mistake was in the
SCRIPT_DEPEND=h5diff$(EXEEXT) $(H5PDIFF) $(srcdir)/testh5diff.sh
$(srcdir)/testh5diff.sh no longer existed. It is now generated in the
current built directory from $(srcdir)/testh5diff.sh.in (which configure
takes care of).

I updated the dependance to
SCRIPT_DEPEND=h5diff$(EXEEXT) $(H5PDIFF) testh5diff.sh
and that fixes the error.
