Previously, x.py would unconditionally run x.py build to get the
help message. After #76165,
when checking the CI stage was moved into Config, that would cause an
assertion failure (but only only in CI!):

thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `1`,
 right: `2`', src/bootstrap/config.rs:619:49

This changes bootstrap to only generate a help message when it needs
to (when someone passes --help).

r? @Mark-Simulacrum
This should fix the CI failures in #76797 and #75991.
