handover_test: set a fake osmo_mgcpc_ep_ci pointer

The handover_fsm activates voice on a target lchan only when the source
lchan has an osmo_mgcpc_ep_ci pointer for the BTS side. Since that
struct is opaque, set a fake pointer and override the
osmo_mgcpc_ep_ci_name() function so that the pointer is never
dereferenced.

This more accurately models the RTP stream setup events during handover.
