x11-toolkits/tepl: Fix build with USE_GNOME+=introspection:build
Fix the following build error I was having:
> Building package for tepl-4.0.0_1

- Error code 1
I suspect this build error only occurred if other GNOME components had
been built with OPTION GTK2 disabled. Regardless, introspection is
clearly a build dependency that hadn't been declared.
