check for systemd using sd_booted() semantics
The existing code determines if systemd is in use by looking at the
distribution name and version. This is prone to error because:
- RHEL derivatives other than CentOS (e.g., Scientific Linux) will fail
this test
- Distributions that are not derived from RHEL also use systemd
This patch makes cloud-init use the same logic that is used in systemd's
sd_booted() method
