Previously, an incantation like `bpfmt -o <$BAD_BP` would print to
stderr as expected, but then it would exit with 0. This is different
than the behavior of `bpfmt -o $BAD_BP`, which correctly exits with a
non-zero status code (in addition to printing the issues to stderr).
Test: m bpfmt; out/soong/host/linux-x86/bin/bpfmt -o <$BAD_BP; echo $?

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.
