When running xfstests on a kernel configured with CONFIG_AIO=n, all
AIO-related tests fail, often due to an error similar to the
following:
error Function not implemented during io_setup
This affected at least the following tests: generic/036,
generic/112, generic/113, generic/198, generic/207, generic/208,
generic/210, generic/211, generic/239, generic/323, generic/427,
xfs/240, xfs/241.
Fix this by enhancing the 'feature' program to allow testing for
asynchronous I/O support, then skipping all AIO-related tests when
AIO is unsupported.
This change is useful because CONFIG_AIO is sometimes disabled to
reduce the kernel's attack surface (e.g. see
https://android-review.googlesource.com/#/c/292158/).
