Writing the ninja file to a byte buffer causes a significant amount
of time to be spent in memmove when growing the byte slice. Write
the file directly to disk instead.
This also fixes some unhandled error warnings, which become more
likely when doing disk IO instead of byte buffer writes.

Blueprint is a meta-build system that reads in Blueprints files that describe
modules that need to be built, and produces a
Ninja manifest describing the commands that
need to be run and their dependencies. Where most build systems use built-in
rules or a domain-specific language to describe the logic for converting module
descriptions to build rules, Blueprint delegates this to per-project build
logic written in Go. For large, heterogenous projects this allows the inherent
complexity of the build logic to be maintained in a high-level language, while
still allowing simple changes to individual modules by modifying easy to
understand Blueprints files.
