Update dependencies (#54)

Update all dependencies,
use Go 1.18 to build and test,
and delete outdated `bindata` clause in Makefile
(we switched to `go:embed` in #50).

Other minor changes:

- Fix the golint import path
  (it switched to golang.org/x/lint long before it was deprecated)
  and fix the failing lint check.
  (Switching from golint to revive is out of scope for this PR.)
- Delete .envrc -- this was transitional for when Go modules were
  optional.
