[8/8] test-lib tests: assert 1 exit code, not non-zero

Commit Message

Ævar Arnfjörð Bjarmason June 14, 2021, 10:48 a.m. UTC

Improve the testing for test-lib.sh itself to assert that we have a
exit code of 1, not any non-zero. Improves code added in
0445e6f0a12 (test-lib: '--run' to run only specific tests,
2014-04-30).
