Remove NETSCAPE_HANG_BUG.

It dates to 2000 from upstream and is only used when serving client auth to
Netscape. It will also get in the way when we get to merging DTLS and TLS
handshake functions because NETSCAPE_HANG_BUG is not valid for DTLS as it is
(the handshake fragmentation code will get confused).

Removing per comment on https://boringssl-review.googlesource.com/#/c/2602/
