[Buildroot] [PATCH 3/4] support/testing/tests: fix tests to use infra.img_round_power2()

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

All the tests that are using if=sd as a Qemu options are changed to
use infra.img_round_power2() instead of simply extending the size of
the image to the next MB boundary, which is not longer sufficient with
Qemu >= 5.1.
