crosh: Make sure command history is saved after typing "exit"
Currently, crosh exits without saving the history when "exit" is
typed (using Ctrl-D works).
This patch modifies exit_cmd to use a variable to break the main
command loop in repl.
BUG=chromium:380538
TEST=Open crosh, enter "random1234", "exit". Open crosh again,
press "up" twice, check that "random1234" then "exit" appears.
