* Add support for NRestarts counter introduced in systemd 235
`.service` units increment this counter any time the Restart= condition is
triggered.

* cpu: Add a 2nd label 'package' to metric node_cpu_core_throttles_total
This commit fixes the node_cpu_core_throttles_total metrics on
multi-socket systems as the core_ids are the same for each package.
I.e. we need to count them seperately.
Rename the node_package_throttles_total metric label `node` to `package`.
Reorganize the sys.ttar archive and use the same symlinks as the Linux
kernel. Also, the new fixtures now use a dual-socket dual-core cpu w/o
HT/SMT (node0: cpu0+1, node1: cpu2+3) as well as processor-less
(memory-only) NUMA node 'node2' (this is a very rare case).

* cpu: Use the direct /sys path to the cpu files.
Use the direct path /sys/devices/system/cpu/cpu[0-9]* (without symlinks)
instead of /sys/bus/cpu/devices/cpu[0-9]*.
The latter path also does not exist e.g. on RHEL 6.9's kernel.

Linux "guest" metrics for VMs are already accounted for in node_cpu
`user` and `nice` metrics. Separate these into their own metric to
avoid duplication of data.
