crio_serial: Symlink runc before installing crio

It appears that runc is now installed by default on fedora nodes. This
conflicts with crio installer, that only installs runc to /usr/local/bin
if not already installed
(https://github.com/cri-o/cri-o/blob/a91b943496f87a1d34a6118d035195be69557842/scripts/get#L236-L238).

However, the runc path is then required to be /usr/local/bin/runc for
the script to complete
(https://github.com/cri-o/cri-o/blob/a91b943496f87a1d34a6118d035195be69557842/scripts/get#L247-L250).

/usr/local/bin/runc is also the required runc for the nodee2e installer:
