[Buildroot] [PATCH 21/27] autobuild-run: move check_version() to Builder class

[Atharva Lele <itsatharva@gmail.com>]

Upcoming patch from Thomas needs check_version() to
use http_url. As that is inside Builder class and check_version()
is only used inside Builder class, move it inside the class.

Also remove the redundant call to check_version() from main().
We already call check_version() in run_instance(). Also the fact
that we cannot call check_version() in main() since the builder
class object is not defined at that point.
