telnetd: don't exit if waitpid() returns 0.
Noticed while using telnetd to manually test some telnet fixes: telnetd would sometimes exit when I'd disconnect because it couldn't find pid 0 on its list of sessions. I've not seen obscure exits because select() times out, but I've also changed that `return` to an error_exit() so we'll at least know what's happened if that ever occurs. Also use <arpa/telnet.h> rather than manually #define'ing its constants, use the FLAG() macro throughout, and xsetsockopt(). Don't pointlessly set errno to 0 at the start of main and then never look at it again.
