[release-branch.go1.18] cmd/compile: fix re-export closure

For hidden closure built during stenciling to implement a function
instantiation, the function may come from other package, not local
package, which causes the ICE for code that re-export the hidden closure
after inlining.

To fix it, use the closure package for export writer when writing out
the closure itself.

Fixes #51423
