libiptc: remove typedef indirection

Don't you hate it when iptc_handle_t *x actually is a double-indirection
struct iptc_handle **? This also shows the broken constness model, since
"const iptc_handle_t x" = "iptc_handle_t const x" =
"struct iptc_handle *const x", which is like no const at all.
Lots of things to do then.
