Add test-eapol program that can be used for fuzzing the EAPOL-Key
Supplicant and Authenticator implementations. This tool can write
Supplicant or Authenticator messages into a file as an initialization
step and for the fuzzing step, that file (with potential modifications)
can be used to replace the internally generated message contents.

The TEST_FUZZ=y build parameter is used to make a special build where a
hardcoded random number generator and hardcoded timestamp are used to
force deterministic behavior for the EAPOL-Key operations. This will
also make the implementation ignore Key MIC and AES keywrap errors to
allow processing of modified messages to continue further.
