Add stubs for POSIX asynchronous io that return -1 and set errno to ENOTSUP. The functions and structures in aio.h are required by the _POSIX_ASYNCHRONOUS_IO Option as detailed in Section E.1 of IEEE-1003.1-2017. The _POSIX_ASYNCHRONOUS_IO interface is required for PSE51, PSE52, PSE53, and PSE54 conformance, and is otherwise mandatory for any POSIX conforming system as per Section A.2.1.3 of IEEE-1003-1.2017.
