fetch set_head: refactor to use remote directly

As a preparatory step to use even more properties from the remote
struct, refactor set_head to take the entire struct as a parameter,
instead of the necessary bits. This also allows consolidating the use of
gtransport->remote in set_head, making the access of the remote's
properties consistent in the function.
