keyword: obtain kwtemplater instance via repository at runtime

Wrapper functions of keyword extension are defined in reposetup(),
because they refer to kwtemplater instantiated in reposetup().

This patch makes them obtain kwtemplater instance via repository at
runtime.

This is a part of preparations for defining them statically.
