raw-posix: Remove O_RDWR when attempting to open a file read-only
When we open a file, we first attempt to open it read-write, then fall back
to read-only. Unfortunately we reuse the flags from the previous attempt,
so both attempts try to open the file with write permissions, and fail.
Fix by clearing the O_RDWR flag from the previous attempt.
