Misc fixes

[dead10ck]

• fix: handle process shutdown with limited permissions

Certain platforms like Android do not have permission to list all child processes. In this instance, just continue

• remove dsa keys from test setup

DSA has been removed from openssh for some time now, and this causes running tests on newer machines to fail

@dwoz How do you feel about removing dsa keys from salt-factories ?

@dead10ck Even though the failures may not be due to your changes, can you look into why the tests are failing, wondering about that 3006.0 and 3007.0 given those are not the most recent versions of those branches

[dmurphy18]

@dead10ck Plan tp merge in your changes, but have to fix up the GitHub Actions , for example: Python 3.7 and 3.8, need to go, both EOL. Once that is fixed, will update / refresh this PR and it should build / test fine.
