Archive old migrations

[tjkirch]

For reference, the previous archiving: #1540. This makes the same change.

These migrations have already been built and released with Bottlerocket
releases and don't need to be built again.  The build system and os package
currently build everything in the migrations directory, which can take a
significant amount of time with unneeded migrations.

Their source is still useful as a reference, and the files are small, so it's
worthwhile keeping them in-tree rather than having to search git history.

Testing done:

This took build time of the os package from ~232 seconds down to ~197.

The contents of the migrations rpm went from all current migrations:

> rpm -qlp bottlerocket-x86_64-migrations-0.0-0.x86_64.rpm
/x86_64-bottlerocket-linux-gnu/sys-root/usr/share/migrations
/x86_64-bottlerocket-linux-gnu/sys-root/usr/share/migrations/migrate_v1.1.0_kubelet-cloud-provider
...
/x86_64-bottlerocket-linux-gnu/sys-root/usr/share/migrations/migrate_v1.2.0_kubelet-topology-manager

To just the directory, as expected:

> rpm -qlp bottlerocket-x86_64-migrations-0.0-0.x86_64.rpm
/x86_64-bottlerocket-linux-gnu/sys-root/usr/share/migrations

I also confirmed the resulting image is still healthy.
