Charles N Wyble 2d9c66138a fix: correct package name from sbsigntools to sbsigntool 
The package name in Debian repositories is sbsigntool (singular), not
sbsigntools (plural). This typo was causing ISO builds to fail with:
  E: Unable to locate package sbsigntools

Files fixed:
- config/package-lists/knel-football.list.chroot - package list
- tests/unit/secureboot_test.bats - test reference
- docs/TEST-COVERAGE.md - documentation
- docs/PRD.md - requirements documentation
