Rex::Hardware::VirtInfo does not handle stuff properly outside of Linux

Describe the bug

Rex::Hardware::VirtInfo assumes that it is being ran on Linux and does not properly use Rex::Inventory::Bios::get, which is the proper cross platform manner to the non kernel module info this module uses.

That said Rex::Inventory::Bios::get does not work as non-root so grabbing when it can via the relevent items under /sys on Linux works.

See https://github.com/RexOps/Rex/pull/1599/files for a fix for this.

Similarly $modules is fetched in a Linux specific manner. Should be /sbin/kldstat on FreeBSD.

The module check for kvm should only work on Linux.

Expected behavior

Works in a cross platform manner via dmidecode via Rex::Inventory::Bios::get.

How to reproduce it

Using on something other than Linux such as FreeBSD.

Code example

use Rex; use Rex::Commands::Gather; dump_system_information;
