* test: use `T.TempDir` to create temporary test directory
This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `ioutil.TempDir`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

t.TempDir fails to perform the cleanup properly because the folder is
still in use

This PR upgrades our CI images and fixes some affected tests.
- upgrade go-machine-image to premade latest ubuntu LTS (ubuntu-2004:202111-02)
- eliminate go-machine-recent-image (no longer necessary)
- manage GOPATH in GNUMakefile (see https://discuss.circleci.com/t/gopath-is-set-to-multiple-directories/7174)
- fix tcp dial error check (message seems to be OS specific)
- spot check values measured instead of specifically 'RSS' (rss no longer reported in cgroups v2)
- use safe MkdirTemp for generating tmpfiles
NOT applied: (too flakey)
- eliminate setting GOMAXPROCS=1 (build tools were also affected by this setting)
- upgrade resource type for all imanges to large (2C -> 4C)
