compiler: don't crash if imported package imports this one

When building a test it's OK if test code imports a package that
imports this one. The go tool is supposed to catch cases where this
creates an impossible initialization order. The compiler already has
code to permit this in Gogo::add_import_init_fn. This CL avoids a
compiler crash on a similar case when writing out the export data.

I have no test case for this. Basically it pushes a compiler crash
into an error reported elsewhere.

Problem was reported by Tony Reix.
