Subject: [PATCH 1/2] fix(ci): fail the relinker test step when no test is
 registered

The relinker-only test step runs ctest without --no-tests=error, so a configuration that registers no test passes with 'No tests were found'. The sibling steps for the register-context, write-watch and relinker-asan tests already pass that flag. ctest 3.25.1 exits 0 without it and 8 with it when no test is found.

Subject: [PATCH 2/2] test(ci): require the relinker test step to fail on zero
 tests

The test reads the relinker ctest line of build.yml and checks that it passes --no-tests=error. Against the previous line it fails.
