Change to be more specific in choosing update file

This change might prevent another update*.sh script from being executed since it is just looking in the root directory. 

This would require naming the update the same update*stratux*v*.sh
i.e.: update-stratux-v0.7b4-f98a8d58c6.sh

Just a bit more safety...

init.d-stratux
