Keep /etc/sysconfig as the fallback, but pick more suitable
values for various Linux distros.

I can't vouch for all of these, but from my limited memory and
search-engine-fu I think you're right here.  There might be more and
more caveats when migrated to systemd for example, especially with
custom envvar files, but that's beside the point here.

I've just looked at what the official package in each distribution is
doing:

https://git.alpinelinux.org/aports/tree/community/libvirt/APKBUILD#n131
https://github.com/archlinux/svntogit-community/blob/packages/libvirt/trunk/PKGBUILD#L93-L101
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-emulation/libvirt/files/libvirtd.confd-r5#n1
https://salsa.debian.org/libvirt-team/libvirt/-/blob/debian/latest/debian/patches/debian/Debianize-systemd-service-files.patch#L48

We can always tweak things later, of course.

Thanks for the review! I'll push the patches now :)
