Fixed file cleanup during make distclean / make check.
Description:
The h5jam Makefile and the h5importtestutil.sh script both included cleanup
steps that removed "*.txt" from the directory. This resulted in the new
CMake specific configuration file, CMakeLists.txt, getting blown away by
make distclean (for h5jam) and make check (for h5import).
I've removed the *.txt from the h5jam Makefile as the directory looks to be
getting cleaned appropriately without it, and I've modified the h5import
script h5importtestutil.sh to point to the specific .txt files to clean.
