Add DESCRIPTION and EXRESULT to new simple_tests includes

Some of the include files added to simple_tests recently don't live in
one of the main include directories (includes/, includes-preamble/ or
include_tests/) which lets test-parser-simple-tests.py fail because
those files don't contain EXRESULT.

Instead of adding more exceptions to test-parser-simple-tests.py, this
patch adds DESCRIPTION and EXRESULT to those include files.
