Remove the gosec Makefile target.

This is not managed by golangci-lint, which does it's own verisoning. The
version in golangci-lint likely won't match this version, so they're most likely
mismatched anyway.

Given that this Makefile target isn't used, we should drop it in favor of `make golangci-lint`
for consistency.
