Subject: [PATCH] pre_build_hook: Introduce USE_DOCKER option

The build system uses Ubuntu Trusty, which is not properly supported
by Docker on AArch64 architecture.
Introduce a new environment variable for enabling/disabling build
containerization, and disable by default said variable for AArch64.

This requires a slight rework of the pre_build_hook script.

NOTE: Setting USE_DOCKER to false will build the packages on the host
machine directly.

AArch64 WARNING: This build will install packages automatically!
