ci: fix RPM path handling and add QEMU boot test

Fix missing --package rpm specification in CI workflow and add QEMU
boot testing to validate converted images.

Changes:
- build-rpm.yml: Export RPM path via GITHUB_OUTPUT for test step
- Makefile: Pass CRYPTPILOT_FDE_RPM to test-convert.sh via --rpm flag
- test-convert.sh: Add test_qemu_boot() function to verify images
  boot correctly using QEMU container (ghcr.io/qemus/qemu)
  - Tests for login prompt (success) or emergency shell (failure)
  - 2-minute timeout for boot completion
  - Full boot log output for debugging
