community/virt-manager: refactor dependencies for virt-install
The dependencies for the virt-install subpackage seemed to be wrong as py3-libvirt and py3-libxml2 were required at runtime by virt-install but not declared in APKBUILD. While digging into it a bit more it seems some a bunch of libraries not required by virt-install were also getting pulled in. I was trying to minimize dependencies for virt-install for headless deployments where it may be useful but virt-manager is not required. I have built and tested from the updated build locally and seems to be working as intended.
