recipes/golang: improve reproducibility

Refer [1], cgo will embeded cgo_ldflags in the intermediary output,
which make content ID will be incfluenced by cgo_ldflags.
'--sysroot=xxx' includes build path, which will make the binary not
reproducible, these recipes can build successfully without --sysroot, so
remove it
