Two bugs fixed:

1) We werent checking for failure on execlp() of shutdown
2) We assumed that /sbin was in the PATH, as otherwise one cannot execute shutdown.
   This is a flawed assumption, particularly in the case of running Opie as a nonroot
   user.  In the case of OZ 3.1rc3.1, /etc/profile no longer puts the sbin dirs in the PATH
   (it never should have in the first place), and opie doesnt source $HOME/.profile in its
   startup script, which resulted in the shutdown app failing to reboot or shutdown.
   Fixed by using execle rather than execlp, and specifying /sbin and /usr/sbin as the executed
   path for shutdown.
