install_terraform: Break the redhat install-deps symlink

TASK [install_terraform : Install Terraform Dependencies] **********************
[WARNING]: Updating cache and auto-installing missing dependency: python3-apt
fatal: [localhost]: FAILED! => {
    "changed": false,
    "cmd": "update",
    "rc": 2
}
MSG:
[Errno 2] No such file or directory: b'update'

install-deps/redhat/main.yml was a symlink to
install-deps/debian/main.yml . When commit 42514aa
("install_terraform: fix missing deps") added the "apt"
step to install-deps/debian/main.yml, it also appeared in
the redhat/main.yml script unintentionally.

Fixes: 42514aa ("install_terraform: fix missing deps")
