selftests/landlock: Add hostfs tests
Add tests for the hostfs filesystems to make sure it has a consistent
inode management, which is required for Landlock's file hierarchy
identification. This adds 5 new tests for layout3_fs with the hostfs
variant.
Add hostfs to the new (architecture-specific) config.um file.
The hostfs filesystem, only available for an User-Mode Linux kernel, is
special because we cannot explicitly mount it. The layout3_fs.hostfs
variant tests are skipped if the current test directory is not backed by
this filesystem.
The layout3_fs.hostfs.tag_inode_dir_child and
layout3_fs.hostfs.tag_inode_file tests pass thanks to a previous commit
fixing hostfs inode management. Without this fix, the deny-by-default
policy would apply and all access requests would be denied.
