CMakeLists.txt: don't require hardening-check --help to exit 0

hardening-check --help returns exit code 1, so the previous
hardening_check_help_result EQUAL 0 guard skipped parsing the help
output entirely. As a result, architecture-specific flags such as
--nobranchprotection on x86_64 were never added to the test command.

Parse the help output regardless of exit code; the option-string regex
checks are sufficient.
