authfs: support multiple threads

This change adds the -j option to let authfs run in multiple threads.

The bad news is even sequential read is sigificantly slower (2x-ish).

Note that this change does not enable -j anywhere.

Bug: 220386264
Test: ls /proc/`pidof authfs`/tasks  # show multiple threads
Test: Read large file. Time was ~2x-ish with -j2. (bad)
