[PATCH 2/3] tests/functional: Convert ARM bFLT linux-user avocado test

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Straight forward conversion. Update the SHA1 hashes to
SHA256 hashes since SHA1 should not be used anymore nowadays.
Expose cpio_extract() in qemu_test.utils for possible reuse.

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
---
Missing meson plumbing, i.e. adding to tests_arm_thorough[]
