cmd/compile: mark closure DUPOK if the outer function is

If a function is DUPOK (e.g. an instantiation of a generic
function) and contains closures, the closure also needs to be
DUPOK. Otherwise, when the outer function is included in multiple
packages, the closure will also be included in these packages, and
the linker will dedup the outer function but not the closure,
causing duplicated symbols. In normal builds it is mostly still ok
as these closure symbols are only referenced by indices. But in
shared build mode all symbols are named and kept live, causing an
error.

Should fix the shared build mode.
