[Buildroot] [PATCH v2 2/5] autobuild-run: make prepare_build() clean the output directory used for reproducibility testing

[Atharva Lele <itsatharva@gmail.com>]

The previous patch introduced a new output directory for the second build in a
reproducibile build test. This patch will make sure that it is cleaned before
the subsequent build process begins.
