This fixes various issues in botfs's `openSecure` implementation for Linux, particularly: - Added missing `O_CLOEXEC` flag to `openat2()` flags - Added EINTR retry loop to follow the stdlib's `OpenFile()` implementation. - Remove `O_CREATE` from `ReadFlags`, and convert it to a pseudo-enum so we can accurately predict intent (see next item) - Pass `0` mode to `openat2()` when reading (see above) - Renamed confusingly named `OpenMode` to `OpenFlags`, because it corresponds to flags, not file modes. - Fixed coincidentally correct misuse of `unix.O_RDONLY` Note that while removing `O_CREATE` from read flags is technically a breaking change, we still automatically files downstream as needed. This results in a "new" debug-level log, but not any actual behavior change.
