ash: fixes to handling of ctrl-C in read builtin

Consider this script:

   while read -r; do echo $REPLY; done
   echo hello

There are currently two problems with this when the read is interrupted
by ctrl-C:

- The error return code is 0 when it should be 130;
- The echo command is executed.

Fix these issues by propagating the control event to the process that
would have caught it if the read builtin hadn't grabbed keyboard input.
