[Buildroot] [PATCH] utils/test-pkg: allow to override the default build directory with an environment variable

[Thomas Devoogdt]

From: Thomas Devoogdt <thomas.devoogdt at barco.com>

Currently, there is one way to override the ${HOME}/br-test-pkg default,
using the --build-dir argument. But when doing frequent test runs, it's
just easier to force it with an environment variable, so add it.
