Title: Fix is_virtual check in ntp.conf templates

is_virtual fact must be checked using a string comparison.

The previous logic would resolve true if the is_virtual fact was
defined. This meant that on servers where is_virtual was defined as
"false", the vm-only snippet was still inserted into the template.
