api/packet: change default ARM server

[tormath1]

c2.large.arm are deprecated too and CI is failing with:

2021-11-22T09:31:56Z kola: creating new machine for semver check: couldn't create device: POST https://api.packet.net/projects/2c850bb4-70b4-4dcd-b60f-2d0be86d0ae4/devices: 422 No available servers with plan c2.large.arm in facility sv15

c2.large.arm is deprecated in favor of: c3.large.arm.

We also need to switch the region to Dallas or Washington DC for ARM64 in https://github.com/flatcar-linux/scripts/blob/main/jenkins/kola/packet.sh because these two are the only ones where hourly availability is: https://metal.equinix.com/product/servers/c3-large-arm/

@pothos good catch thanks - in this case, let's move everything to Dallas (da11) both instance types (c3.small.x86 and c3.large.arm) are available within this facility.

For PXE booting it helps when the instances are in the same data center or region, I would not move c3.small.x86 to Dallas because it's almost 3000 km away - the exception for arm64 should also annotate that it is a temporary measure until there is c3.large.arm availability in SJC/SV.
