CI uses make check, build.ps1 copyright

- Makefile: make the "check" target exit non-zero on a test mismatch
  instead of merely printing FAILED.
- CI: rely on "make check" / "build.ps1 -Target check" exit codes rather
  than reimplementing the test/diff logic in YAML; compile-cover the
  OpenMP/SysV-shm path on Linux by building initrom and userom.
- build.ps1: add the copyright/license header.
