main: require argv[0]

sure, linux has been providing argv[0] by default for a while now. other
OSes may not be as forthcoming though, and relying on the OS to create a
world in which we can just make assumptions we could test for instead is
unnecessarily lazy. we *could* default argv0, but that's a little silly.

notably we abort instead of returning normally to avoid confusions where
a caller interprets our exit status like a Worker build results bitmask.
