Five tests covering behaviour the harness could reach but nothing
exercised.  Each was verified to fail against the code it guards, by
reverting the fix or sabotaging the exact line; where a first attempt
passed against broken code, the fixture was wrong and was rebuilt.

  post-link                    first coverage of the subcommand at all
  local-vs-export              local symbols must not match exports
  symvers-parse-error          Module.symvers parse error line numbers
  checksum-debug               the --debug-checksum format klp-build reads
  function-removal             the "no correlation" path

local-vs-export tests the behavior of commit 86a697572c62 ("objtool/klp:
Don't match local symbols against exports"), and symvers-parse-error that
of commit 51c1de134863 ("objtool/klp: Fix line numbers in Module.symvers
parse errors").
