Install and start acpid on virtual nodes

Some users may be running various nodes (including master node since
7.0) as virtual machines – acpid allows them to do graceful shutdown or
reboot without using ssh.

The commit introduces custom fact to check if ACPI is available via
procfs on machine. acpid itself is only installed and started if node is
not physical and has ACPI.
