[Make-wifi-fast] Updated LEDE build with airtime patches

The tweaks I usually do are for fine-tuning and can be too difficult for 
the average user.  I made you a custom build and a config file, so you 
could easily have a finely-tuned build.

Toke's build should work well for you.  You have improvements to your 
WiFi stack in your router.  The custom firewall rules I recommended 
before only work if you have a specific set of packages installed, so I 
recommend just removing them.  If you have the dual-src and dual-dst 
settings in your SQM settings, keeping that will benefit you.
