Resolve Go lint tools from GOBIN in run-go-tests

The script located gci, go-critic, staticcheck, and errcheck under
$(go env GOPATH)/bin, but `go install` honors GOBIN, which our Nix dev shell
sets to bin/.go. The installed binaries therefore landed in GOBIN while the
script looked in GOPATH/bin, so every lint step failed with "No such file or
directory". Resolve the tools from GOBIN when it is set, falling back to
GOPATH/bin otherwise.
