block/raw-posix: Build fix for O_ASYNC
Commit eeb6b45d48800e96f67ef2a5c80332557fd45ddb (block: raw-posix image file reopen) broke the build on OpenIndiana. illumos has no O_ASYNC. Exclude it from flags to be compared and instead assert that it is not set where defined. Cf. e61ab1da7e98357da47c54d8f893b9bd6ff2f7f9 for qemu-ga.
