smokey/dlopen: introduce a new testcase
This commit introduces a new testcase into the smokey framework. The
test covers some aspects of adding xenomai-functionality to applications
with dlopen(). It also tests initialization and tunables.
This test also shows a bug in xenomai, so the test will actually fail.
The next commit will fix that again.
