Add new curtin-requirements seed for curtin based installers.

LP: #1798457

[Dimitri John Ledkov (xnox)]

To be read in conjuction with https://code.launchpad.net/~ubuntu-core-dev/ubuntu-seeds/+git/ubuntu/+merge/356996 which creates a dep on `boot` seed, which already has the right kernel names for every arch, and a few other arch specific things. Thus e.g. re-seeding grub here is redundant, however is "useful" because this should be kept in sync mechanically with curtin. And germinate knows how to remove dupes.
