scripts/tags.sh: add ctags magic for declarations of popular kernel type

- Add magic for declarations of variables of popular kernel type like
  spinlock_t, list_head, wait_queue_head_t and other.

- Add a set of specially handled declaration extentions like
  __attribute, __aligned and other.

- Simplify pci_bus_* magic
