Do not propose hibernation on virtual setups

[joseivanlopez]

Problem

The method Kernel#propose_hibernation? was returning true when the system is running over certain virtualized setups like hyper-v. This makes to yast2-bootloader to propose the resume= kernel parameter in such scenarios, , but it should not do it according to https://jira.suse.com/browse/SLE-12280.

• https://trello.com/c/VkjmNIRr/2279-3-yast-bootloader-adds-the-resume-parameter-when-it-shouldnt

Solution

Now Kernel#propose_hibernation? uses the new method Arch#is_virtual? to check whether the system is running on a virtualized setup, does not matter the specific virtualization technology. For now this is enough, but maybe in the future we might need a more fine grained detection. In that case, we could consider to use virt-what utility. For example, to check what is the specific virtualization technology in use (kvm, hyper-v, etc).
