A <channel/> device is basically an UNIX socket into guest. Whatever is sent from the host, appears in the guest and vice versa. But because of that, the length of the path to the socket is important (underscored by fact that we derive the path from domain short name). But there are still cases where we might not fit into UNIX_PATH_MAX limit (usually 108 characters), because the path is derived also from other variables, e.g. XDG_CONFIG_HOME for session domains. There are two components though, that are needless: "/target/" and "domain-" prefix. Drop them. This is safe to do, because running domains have their path saved in status XML and even though paths are dropped on migration, they are not part of guest ABI and thus we are free to change them.
