tests: Build Cmocka from source
Relying on Cmocka packages, which are provided with different OS distributions, may introduce some problems with setup environments across developers (e.g. library version mismatch). Instead, let's build Cmocka from source code, which is now added to git submodules as 3rdparty/cmocka. Please note, that cmake tool is required for building Cmocka (thus also coreboot unit tests).
