When rustc prints an error containing a long type that doesn't fit in a
line, it will write the whole thing in a .txt file and print messages
like:

  note: the full type name has been written to
  'path/to/subsystem/module_name.long-type-11621316855315349594.txt

Long types like core::result::Result<core::pin::Pin<Box<_, Kmalloc,
kernel::error::Error>: pin_init::PinInit<Box<_, Kmalloc>, _> are common
during development, so add a gitignore entry.
