tests: use TESTTMP instead of TESTDIR stable

tests: use TESTTMP instead of TESTDIR

In 57d0c8c3b947, f042d4b263f4, 1e686e55780c, and 5d22cadd1938, new tests were
added that used TESTDIR instead of TESTTMP thereby leading to polluting the
working directory with these temporary files. Now, we use TESTTMP so that they
will be cleaned up properly.
