Subject: [PATCH] bootstrap_sdk: Allow stage1 hooks to decide about updating
 seed SDK

Stage1 hooks will receive a path to a file as a third parameter. They
can use it to tell the bootstrap script to set up catalyst to perform
updates on seed SDK. Contents of the file are ignored - what counts is
that the file exists AND is not empty.
