Adjust the path of the ABI files for firewire.rst to prevent a
documentation build error. Prevents this problem:

Sphinx parallel build error:
docutils.utils.SystemMessage: Documentation/driver-api/firewire.rst:22: (SEVERE/4) Problems with "include" directive path:
InputError: [Errno 2] No such file or directory: '../Documentation/driver-api/ABI/stable/firewire-cdev'.
