wings: Script does not detect openvz and lxc at the same time

[sinjs]

Describe the bug
Docker can't run on openvz and lxc. The script detects if the user is running openvz or lxc but not if they are using them at the same time:

$ virt-what
openvz
lxc

To Reproduce
Get a machine using lxc and openvz and try to install wings.

Expected behaviour
The script should complain about the virtualization type

The fix might be as simple as checking for *openvz* | *lxc*), instead of checking for openvz | lxc). But not gonna lie it's an oddball case.

Do you run LXC containers inside OpenVZ or the other way around?

[sinjs]

I don't run any of these. I just opened this issue due to the bug reports in the discord server. Check the discord link in the original issue

Update: someone has got another type of LXC

$ virt-what
virtual machine lxc
