Add a flag "USE_SYSTEM_CMOCKA" in the Makefile of tests. (default 1)
If USE_SYSTEM_CMOCKA=1, we will check if the system has Cmocka module,
and link it directly. If the system doesn't have Cmocka, we will set the
flag to 0 and print a warning message.
If USE_SYSTEM_CMOCKA=0, we will build Cmocka from 3rdparty source code.
