codegen: Require at least one interface file to be specified

Browse Source 
Previously, running `gdbus-codegen` with no arguments would exit
successfully with no output. While technically correct, that seems
unhelpful.

Require at least one interface file to be specified, so the user gets an
error message if they don’t specify any.
