usage: allow dying without writing an error message
Sometimes code wants to die in a situation where it already has written
an error message. To use the same error code as `die()` we have to use
`exit(128)`, which is easy to get wrong and leaves magic numbers all
over our codebase.
Teach `die_message_builtin()` to not print any error when passed a
`NULL` pointer as error string. Like this, such users can now call
`die(NULL)` to achieve the same result without any hardcoded error
codes.
Adapt a couple of builtins to use this new pattern to demonstrate that
there is a need for such a helper.
