builtin/merge: switch tree functions to use object_id

The read_empty and reset_hard functions are static and their callers
have already changed to use struct object_id, so convert them as well.
To avoid dependency on the hash algorithm in use, switch from using
EMPTY_TREE_SHA1_HEX to using empty_tree_oid_hex.
