Remove rt_svc_descs pointer from global scope

A pointer to rt_svc_desc_t is defined both in the function
handle_runtime_svc() and globally. Since the value of the
pointer RT_SVC_DESCS_START is defined by the linker and
never changes make this definition local in both
handle_runtime_svc() and runtime_svc_init() to reduce the
number of loads
