[Buildroot] [PATCH v4 24/30] autobuild-run: create reason file on build failures

[Atharva Lele <itsatharva@gmail.com>]

When a build fails, we calculate the reason of failure on
the server side as well as client side. To solve this redundancy
we only calculate on the client side and submit a file which
contains the reason of failure.
