Add support to test that the root passowrd is working as expected.
- Buildtime test: Check the hash present in the generated '/etc/shadow'.
- Runtime test: Build an armv7 image and try to login with a password.

Changes:
v1 --> v2:
- Fix coding style to pass flake8 test
v2 --> v3:
- Add 'BR2_TARGET_ROOTFS_CPIO=y' to the .config
- Add myself as developer for this test
- Fix a typo 'has' --> 'hash'
- Use assertEqual(a, b) instead of assertTrue(a == b)
- Update .gitlab-ci.yml
