tests: Add some basic warnings and fix resulting issues
The current test framework builds the test code without any warnings at all, which isn't great -- we have already slipped in some cases of non-void functions not returning a defined value, for example. It would likely be overkill to try to use all the same warnings we use for normal coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's __wrap_xxx() mock functions unnecessarily cumbersome to work with, and other things like -Wvla may be appropriate for firmware but is probably too aggressive for some simple test code). Therefore, let's just add some of the stuff that points out the most obvious errors.
