fix shine install -L

[thiell]

Should only perform the install on the local node (like -n $HOSTNAME)

[degremont]

-L is already implemented as -n $HOSTNAME internally.

This patch should do the trick:

    Ticket #209: support -L flag for 'install' command

    Call init_execute() also for 'install' command like
    all other FSLiveCommand classes.
