Create a repo w/o history as well
Create a repo w/o history as well

This CL adds a second task to the createArchieve that will
create a repository w/o the history + prebuilts.

I've also modified the current task not to copy prebuilts
twice. It will just pull them from prebuilts folder when
creating the big bundle zip.

Bug: N/A
Test: build works
