isofs: port to libdiskfs' node cache

* isofs/inode.c: Drop all cache-related code.
(diskfs_user_make_node): New function.
(calculate_file_start): Check for `record' being null.
(cache_id): New function.
(read_node): Rename to diskfs_user_read_node and adopt accordingly.
(diskfs_try_dropping_softrefs): Rename to diskfs_user_try_dropping_softrefs.
* isofs/isofs.h (struct lookup_context): New definition.
(cache_id): New declaration.
* isofs/lookup.c (diskfs_lookup_hard): Adjust accordingly.
* isofs/main.c (fetch_root): Likewise.
