runtime: make module typemaps visible to the GC
The map[typeOff]*_type object is created at run time and stored in
the moduledata. The moduledata object is marked by the linker as
SNOPTRDATA, so the reference is ignored by the GC. Running
misc/cgo/testplugin/test.bash with GOGC=1 will eventually collect
the typemap and crash.
This bug probably comes up in -linkshared binaries in Go 1.7.
I don't know why we haven't seen a report about this yet.
Fixes #17680
