Subject: [PATCH] OpenFile portal: do not use O_PATH fds
Using O_PATH requires correctly specifying whether the fd is writable or
not. Stating that the fd is writable without it actually being writable
results into rejection on xdg-desktop-portal side. Other implementations
like xdg-open or gtk have also moved away from O_PATH fds so this will
make a matching implementation and avoid possible rejections from xdp.
Fixes: QTBUG-113143
