eapol-fuzzer: Resolve circular library references with --start-group

src/crypto/libcrypto.a and src/tls/libtls.a have circular references
and will need special handling with the linker at least for the time
being. This could be cleaned up eventually, but for now, provide a
mechanism to get the program linked.

This was already done in tests/Makefile, but tests/eapol-fuzzer/Makefile
needs the same.
