MT#60588 redis: allocate `sdp_origin` using g_malloc

Allocate sdp_origin members using `str_init_dup_str()`
which uses g_malloc, so that when freeing the sdp_origin
structure later in `sdp_orig_free()` it doesn't inadvertently
lead to the seg fault.

Otherwise if any member isn't recovered (e.g. username)
it remains pointing to NULL with 0 len, which will be gracefully
handled in `str_free_dup()`.
