gotools: Workaround non-reproduceability of automake

The regen bot recently flagged a difference in gotools/Makefile.in.
Trying it locally, it seems pretty random

	* Makefile.am (install-exec-local, uninstall-local): Add goals
	on the else branch of if NATIVE to ensure reproducibility.
	* Makefile.in: Regenerate.
