Update k8s-await-election to fix golang crashes

Older versions of k8s-await-election would lead to crashes on ubuntu systems.
The golang version used to build (1.14.0) was not recognizing the ubuntu kernel
version, applying a workaround for an already fixed issue that would end in
random crashes.

See: golang/go#37436
