Previously, the Wine implementation of `NtOpenFile` would fail to open read-only files for `FILE_WRITE_ATTRIBUTES` access in wine-server, because it would attempt to open the file with `O_RDWR` or `O_WRONLY` access.
This patch-set adds test cases to highlight the issue, and solves it by only opening the file with write access where necessary.

-- v6: server: Allow to open read-only files with FILE_WRITE_ATTRIBUTES server: Open files for writing with O_WRONLY not O_RDWR if FILE_READ_ATTRIBUTES is also requested
