linux-crashdump isn't built for arm64

[dann frazier]

[Impact]
kdump works fine on arm64 these days, but end users have to manually install the various packages to make it work vs. just installing linux-crashdump like on other architectures.

[Test Case]
On an arm64 system:
sudo apt install linux-crashdump

[Fix]
Add the necessary debian/control bits to build this package on arm64.

[Regression Risk]
We're making a package available on arm64 that wasn't previously - if that package is broken for some reason, it won't be a regression.
