[Buildroot] [git commit] support/testing/tests: fix tests to use infra.img_round_power2()

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=abe32cfdf0dda17af10d290fe1cb33c0fc60a076
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
