* Allows removing multilib from docker images
* Run properly in aarch64 host docker
containers for testing on Rasberry Pi.
* Small sticky-keys fix to initialize w/ correct
constant for max uin32_t value.
Quick release for sticky keys failed for non-layer keys. The sticky key
was released just before the key that was supposed to be modified was
handled.
The issue was caused by an error in the sticky key logic, which released
the sticky key before handling the key up event.
Fixes#696.
