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.
