The compiler was canonicalizing unnamed types of the form
struct { i int }
across packages, even though an unexported field i should not be
accessible from other packages.
The fix requires both qualifying the field name in the string used by
the compiler to distinguish the type, and ensuring the struct's pkgpath
is set in the rtype version of the data when the type being written is
not part of the localpkg.
Fixes #16616
