[Buildroot] [PATCH 1/3] support/run-tests: add a mode to only download emulator builtin binaries

[Romain Naour <romain.naour@gmail.com>]

Currently, emulator builtin binaries are downloaded after the rootfs
build by each tests running the emulator (Qemu) on armv5 or armv7.

Due to download quota on the server hosting theses binaries [1]
some GitLab jobs are failing due to "Connection reset by peer" [2]:

  ConnectionResetError: [Errno 104] Connection reset by peer

In a follow up commit, we'll add the possibility to download only once
all emulator builtin binaries to pass them as build artifacts.

As such, we will need to make sure that run-tests only download theses
binaries, and that it does not run the testsuite.

Add such a mode, with a new option, --prepare-only.
