[Buildroot] [PATCH buildroot-test 6/8] autobuild-run: create main method to locally-scope all variables

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

In the current autobuild-run script, all variables created in the 'main'
part are in fact global, even though the script does not intend them to
be. For example, sysinfo is global, even though it is passed as function
argument to run_instance.

To avoid this accidental globalization, create a main method instead.
All variables created therein are now local to that method.
