go: with gcompat in world, binaries can link against glibc

this is probably a bug affecting a bit more than just containerd, but that's the only package we can reproduce it with (for now)

steps:

$ apk add gcompat
$ abuild -r

can be seen with:

$ apk fetch --stdout containerd | tar xOz usr/bin/containerd-shim-runc-v2 | fq -r 'grep_by(.name==".interp").data | toactual'
/lib64/ld-linux-x86-64.so.2
