Fixes#1050
Summary
O_PATHfor intermediate directory descriptors in the ownership-checked path walk where supportedAndroid permits traversal through
/to/sdcardbut does not permit Termux to open/withO_RDONLY | O_DIRECTORY. The hardened destination walk therefore failed before reaching the destination even though the intermediate directories were searchable.
