GHA: self-host by default. Skip jq, nasm, powershell, xslt, vbs

Xslt may never be able to do full self-hosted tests. Powershell succeeds
but doubles the total runtime for the GHA workflow.

We would definitely like jq, nasm, and possibly vbs to be fixed for
self-hosted tests.
Ticket tracking fixes: #662
