sysutils/puppet: use REQUIRE: LOGIN in rc scripts

[mmoll]

Summary

On a newly installed system I did see messages about libraries that could not be found by ruby21. It turned out that the current rc scripts for puppet have REQUIRE: NETWORK set, which means it can run before ldconfig was executed, leading to a non-started puppet agent at startup.
Proposed commit message:

sysutils/puppet: use REQUIRE: LOGIN in rc scripts

The puppet agent will get started later, especially after ldconfig.
