automation: avoid '~' in the temp directory on Windows
If a long-ish username is used, the environment variable ends up with a '~' to
be 8.3 path compatible. That in turn causes a handful of tests (mostly ssh
related) to add quotes around $TESTMP.
I have no AWS experience, so I have no idea if this is the proper way to do it.
But I've hit this problem locally, and redirecting the directory is a
workaround. I don't recall if the directory is created on demand by the test
harness, but presumably if this is configured before the machine boots, Windows
will do it for us.
