fix: revert "feat: [NODE-1521] Move bootloader off dockerhub (#2475)" (…

…#2506)

This reverts commit c582bfe because it
breaks the hourly `//rs/tests/nested:...` system-tests since the
`host-1` VM gets stuck on grub:

This is likely caused by
[using](c582bfe#diff-6580a63795796c85f6d7ac9b194b7543ce61bed207dad770e648fa53bef72ad1R1)
`$fw_path` in `grub.cfg`.
