This change adds 2 tests to make sure that the *_oomprotect variable
sets the protection against OOM killer properly within rc(8) scripts.
This is also adding the first tests for the rc(8) framework. More tests
will be added as we go.

Note: I'm not sure if I got the makefiles right and I probably need to add some mtree entries. If you know how to do that, please let me know ;)
