[sonic_installer] temporary fix: don't migrate packages on aboot plat…

…forms (#1607)

What I did
Skip sonic package migration on aboot platform.

How I did it
Added a warning and skip the migration.

How to verify it
I changed AbootBootloader to OnieInstallerBootloader to test on my Onie device. I don't have Aboot device.
