Add OpenBSD virtualization facts. (#17227)

* Add OpenBSD virtualization facts.

Patch written by @jasperla.

Tested by various people on:
- virtualbox
- vmware esx(i) + fusion
- kvm (smartos + plain linux + a random cloud provider)

This patch is already present in the OpenBSD port of ansible.

* Rework diff to get rid of extra returns.

Requested by @bcoca.

While here, use four-space indentations of all code blocks.

* Set facts even if no match is found.

Discussed with @bcoca.

* Find sysctl via get_bin_path().

Requested by @bcoca.

* Fail if we do not find a sysctl binary.

* Do not fail if a sysctl binary is not found.

Just set empty fact values instead.
Requested by @bcoca.
