[release-branch.go1.10] cmd/cgo: disable GCC 9 warnings triggered by cgo code

GCC 9 has started emitting warnings when taking the address of a field
in a packed struct may cause a misaligned pointer. We use packed
structs in cgo to ensure that our field layout matches the C
compiler's layout. Our pointers are always aligned, so disable the warning

Updates #29962
Fixes #29966
