scraper: remove dead Context/SetContext interface methods

Context() and SetContext() on SNMPScraper have zero call sites — they
were re-introduced by a previous fix subagent after commit 5a347df
had already removed them cleanly. Drop them from the interface and
their implementations in GoSNMPWrapper and mockSNMPScraper; also
remove the now-unused "context" import from scraper.go and mock.go.

go build ./... and go test ./... -race both pass.
