sysstat: fixed libdir-path in spec-file
This update fixes the following issue with sysstat:
- bnc#783886: service unit included hardcoded /usr/lib, however sysstat is installed to /usr/lib64 on 64 bit systems
- bnc#783886: Fixed two typos in spec related to service unit, which prevented successful startup
