[Buildroot] [PATCH v7 1/2] testing/infra: split runtime test into new class

[Matt Weber]

From: Ricardo Martincoski <ricardo.martincoski at datacom.ind.br>

Move the setup of emulator to a new class, which takes the BRTest name.
The original BRTest is renamed to BRConfigTest and is used as a base
class for test cases that don't require a run-time target test. It will
avoid duplicating code / execution time when adding a common class to
test items like the git download infra.

The existing test cases are not impacted as the base and emulator class
are still contained in basetest.

Changes v6 -> v7:
[Peter / Arnout
  - Swapped the class structure to allow all the existing test cases to
    not be impacted

Changes v5 -> v6:
  - Fixed rebase which added extra args being passed to
    self.b.configure() for br2-external support
  - Added additional test cases with class updates committed since v5

Changes v4 -> v5:
  - no changes

Changes v3 -> v4:
  - re-run the automatic replace command

Changes v2 -> v3:
  - new patch
  - search for "RuntimeTestBase" in
    http://patchwork.ozlabs.org/patch/806161/
