[bug-inetutils] BUG-report: here is strange character when logging in by telnet

[yhu2]

when custsomer started telnet service on board, and try to log it from 
PC, there is strange character before login and passwd promp. please 
look at attached 'telnet.jpg'.

root cause is that telnetd wrongly handled TIOCPKT_FLUSHREAD case when 
pseudoterminal runs under packet mode. attachment patch is a fix.

Any comments would be appreciated!
