Call x86-64 __setcontext directly

Since x86-64 __start_context calls the internal __setcontext:

5089: 00000000000417e0   145 FUNC    LOCAL  DEFAULT   13 __setcontext

it should call __setcontext directly.

	* sysdeps/unix/sysv/linux/x86_64/__start_context.S
	(__start_context): Call __setcontext directly.
