tests: Disable -Wmain-return-type for clang

Unit tests fail on clang because Cmocka's main() function is declared
with return type int, but through some of our chain-include games it
sometimes gets coreboot's main_decl.h which declares the function as
void. Compilers have traditionally always been very laissez-faire about
the signature of the main function, but it seems that clang has been
getting more strict by default recently. Explicitly disable the related
warning to shut it up.
