fix incorrect macro reference in PIC plugin

This looks once again copied from the core PIC implementation
(lib/common/picgen.c) without accounting for the fact the core implementation’s
attrs macros are generated dynamically. The plugin generates a single macro,
attrs0, which it was incorrectly calling as attrs1. Related to #131.
