mklive.sh.in: add custom scripts to init

Browse Source 
The added option -H <hooksdir> allows the user to specify a directory
that contains hook scripts which should be run directly after the live
system's init sequence.
This can be used to customize the system (such as e.g. setting a
different default shell)
