lint: remove dot import (go-common)

Spell out the package explicitly.
This commit is totally textual, and does not change any logic.

The swiss-army knife package may serve a kick-start in early
stage development. But as the codebase growing, we might want
to retire it gradually:

  For simple wrapping functions, just inline it on the call site.
  For larger pice of code, make it an independent package.
