Use sockaddr length from fuzzer
Use sockaddr length from fuzzer

Commit 6814cb6a0 made major changes and introduced the
"HonggfuzzNetDriverServerAddress" function which can be defined by
a fuzzer. Unfortunately the connection attempt didn't use the
fuzzer-provided length and thus truncated longer socket address
structures such as "sockaddr_un".
