go tool objudmp -S can't print source code when the executable is built with go build -buildmode=pie. pclntab data is not in elf section .gopclntab, but in .data.rel.ro.gopclntab. .gosymtab has similar problem.

cmd/objdump: fix -S with dynamically-linked executable
4291926 
`go tool objudmp -S` can't print source code when the executable is
built with `go build -buildmode=pie`. pclntab data is not in elf section
`.gopclntab`, but in `.data.rel.ro.gopclntab`. `.gosymtab` has similar
problem.

This fixes issue golang#50269.

CL https://go-review.googlesource.com/c/go/+/227483 was my attempt but it doesn't work everywhere and still have problems.
