image_types_ostree/ota: use hash from ostree commit

Relying on a OSTree branch reference has been problematic in the past
and addressed by adding more attributes to it in commit 202a8c70ba8c
("image_types_ostree: Add a unique ref to fix simultaneous bitbaking.").

However, depening on what kind of OpenEmbedded builds are running in
parallel, even more attributes would need to be taken into account.
Instead of relying on a reference, store the exact ostree commit hash
in a manifest file and reuse it in the do_image_ota deploy task. This
guarantees that the correct reference gets picked even when two builds
with the exact same machine/image name run in parallel.

Note: This gets rid of the second branch name again. If the branch name
with image name is preferred, the variable OSTREE_BRANCHNAME can be
used:
OSTREE_BRANCHNAME = "${SOTA_HARDWARE_ID}-${IMAGE_BASENAME}"
