Change tmpDir when running e2e localmachine test on macOS

[tnk4on]

Fix https://github.com/containers/podman/issues/22360

Does this PR introduce a user-facing change?

Fixed an error starting Podman machine when running e2e localmachine tests on macOS.

The fixes are only to the e2e test file and Doc, no additional tests.

@ashley-cui I think the macOS CI Fail is another cause as it was happening with other PRs. The podman machine actually started without timeout until halfway through.

I added code to check $TMPDIR. Please check.

LGTM, restarted flaking tests, thanks!

Please rebase to pick up the bud test fail, thanks!

@ashley-cui I added some code. Please check.

If TMPDIR=“”, it cannot connect to gvproxy.sock.

so I changed it to return an error.

Also, if TMPDIR is a directory that is not mounted on the podman machine, the bind mount test (e.g. "Volume ops". at basic_test.go) will return an error. Therefore, added check if TMPDIR is included in Machine.Volumes.
