Move virt-* code into their modules

This layout is closer to what most python modules have nowadays.
It also simplifies testing and static analysis setup.

Keep virt-* wrappers locally, for ease of running these commands
from a git checkout.

Adjust the wrapper binaries we install on via packaging to be
pure python, which makes things like running gdb easier.
