Fix ttys, fix device mounting issue in getty, add nerdctl (#222)

## Description

<!--- Please describe what this PR is going to change -->
For some reason I was seeing issues with the 6.6 kernel and ttys when
they are not explicitly set in the linuxkit yaml. Also with the 6.6
kernel, I was seeing issues with the ctr command and character encoding
or something similar. I was getting a lot of weird character when using
it. Moving to nerdctl resolves this issue. Nerdctl is also a lot more
user friendly in general. Also, the getty container was getting
permission denied issues when trying to mount devices. Explicitly adding
a block devices to the linuxkit yaml resolved this.

## Why is this needed

<!--- Link to issue you have raised -->

Fixes: #

## How Has This Been Tested?
<!--- Please describe in detail how you tested your changes. -->
<!--- Include details of your testing environment, and the tests you ran
to -->
<!--- see how your change affects other areas of the code, etc. -->


## How are existing users impacted? What migration steps/scripts do we
need?

<!--- Fixes a bug, unblocks installation, removes a component of the
stack etc -->
<!--- Requires a DB migration script, etc. -->


## Checklist:
