This update for systemd-rpm-macros fixes the following issues:

- Fixed an issue whe zypper ignores the ordering constraints. (bsc#1187332)
- Introduce '%sysusers_create_package': '%sysusers_create' and '%sysusers_create_inline' are now deprecated and the new macro should be used instead.
- %sysusers_create_inline: use here-docs instead of echo (bsc#1186282)
