Tom Cherry 14c2472734 init: degeneralize subcontext init into only vendor_init
This code is more generic than it needs to be and one of the side
effects is that an extra init process is forked for odm_init, despite
it having the same context as vendor_init.  I don't think anything is
going to change regarding that soon, so this change stops forking that
extra process to save its memory and simplifies the code overall.

Bug: 141164879
Test: init still uses vendor_init for vendor_scripts
Test: init unit tests
Test: init only has one subcontext process
