This change fixes an issue where the re-bootstrapping process would overwrite a
newer bootstrap manifest with one that it generates using its older minibp. It
fixes the issue by only generating a new bootstrap manifest right after
rebuilding minibp (as part of the bootstrap process). It then uses an
additional rebootstrap iteration to replace the old bootstrap manifest with the
new one.

Blueprint is a build system component that reads Blueprints files defining
modules to be built, and generates a Ninja build manifest that can be used to
perform all the build actions. It does not dictate or implement much build
policy itself, but rather provides a framework to ease the process of defining
build logic in Go.
The "blueprint" and "blueprint/parser" Go packages contain the functionality
for reading Blueprint files and invoking build logic functions defined in other
Go packages.
The "blueprint/bootstrap" Go package contains just enough build logic to build
a binary that includes Blueprint and any pure-Go (i.e. no cgo) build logic
defined in external Go packages. This can be used to create a minimal Ninja
file that's capable of bootstrapping a Blueprint-based build system from
source.
The "blueprint/bootstrap/minibp" Go package contains code for a minimal binary
that includes the build logic defined in the "blueprint/bootstrap" package.
This binary can then create the Ninja file for the bootstrapping process.
