recover_duts: fix awk error due to line break

Despite being invoked by the shell, awk isn't seeing the second
part of the line;
awk: cmd. line:1: /tcp.*:22 .*ESTABLISHED.*/ { split($5,a,":") ;
awk: cmd. line:1:                                                ^
unexpected newline or end of string

Fix is to append '\' to the offending line to tell the shell
both lines should be passed to awk together.

BUG=none
TEST=invoke /usr/local/bin/hook/check_ethernet.hook from console
     when no SSH connections are present.
     Confirm output does not include awk syntax error.
