configs: drop unused country.dat file from install

I could not find _any_ reference to it in current checkouts of ~every
Proxmox repository.

AFAICT this was copied from pve-installer in pve-installer commit

  f0583fd4e ("copied country.pl form pve-manager")

in 2017 and simply never dropped here afterwards, so it's an unused
leftover.
