Go Ductape Image for Alpine

[panitaxx]

Description of the issue:

When using a binary created in an alpine image the delve cannot be used with the delve duct tape. It causes:

standard_init_linux.go:211: exec user process caused "no such file or directory"

Expected behavior:

Should run normally

Steps to reproduce:

• Build a go program image from alpine linux container
• Add duct-tape as an init container
• run skaffold with:
  command: ["/dbg/go/bin/dlv","exec" ,"<executable>","--headless","--listen=:56268","--log"]

Environment: Ubuntu 19.10

Can you think of a way to determine whether an image is GLIBC or MUSL based? To support distroless-style images, we need to avoid shell scripts.
