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).
