[Buildroot] [PATCH v2 2/3] autobuild-run: initial implementation of do_reproducible_build()

Fri Jun 7 06:46:56 UTC 2019
This new function will call do_build() twice to produce two builds
and then check their reproducibility
Signed-off-by: Atharva Lele <itsatharva at gmail.com>

Changes v1 -> v2:
- make clean outputs to devnull (suggested by arnout)
- remove unnecessary arguments to make clean (suggested by arnout)
