[BusyBox] Small ASH patch

[Tim Riker]

From: http://cnswww.cns.cwru.edu/~chet/bash/NEWS 2.04 release info:

h.  The `read' builtin has a number of new options:
  -t timeout      only wait timeout seconds for input
  -n nchars       only read nchars from input instead of a full line
  -d delim        read until delim rather than newline
  -s              don't echo input chars as they are read
