osbuild-{composer/worker}: exit cleanly

Browse source 
Only panic on compile-time errors (e.g., built for unsupported
architecture). Otherwise, use log.Fatalf(), which is equivalent to
printing and exiting with return code 1. Only ever do this from
main(), in all other cases pass on the error object.

This is mostly relevant when the server disconects, in which case
we'll get EOF, and will now restart cleanly instead of panicing.
