[Support] On AIX, Check ENOTSUP on posix_fallocate instead of EOPNOTSUPP
Summary:
`posix_fallocate` can fail if the underlying filesystem does not support
it; and, on AIX, such a failure is reported by a return value of
`ENOTSUP`. The existing code checks only for `EOPNOTSUPP`, which may
share the same value as `ENOTSUP`, but is not required to.
