This is not what the lib/tst_module.c does. It tries test startwd which
is recorded before the test does chdir() to the newly created test
directory. Otherwise if the test calls tst_tmpdir() the module in the
directory the test was started in will not be found. So we have to
record the test start working directory in tst_tmpdir() and use it here.


Otherwise it looks good.
