libgo: export NetBSD-specific types in mksysinfo.sh
The syscall package depends on many NetBSD-specific types on NetBSD. Teach mksysinfo.sh to export these types. This alone is not sufficient to get the syscall package to compile on NetBSD, but it's a start. Note that the IfMsgHdr type is recapitalized to IfMsghdr, which requires changes in the AIX port. The new capitalization is what's used by upstream in existing NetBSD-specific code and is more consistent with the capitalization of other C structs with the "hdr" suffix. Updates golang/go#38538. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/261739
