Andrew Kaster c6eff55439 Shell: Make sure all tests put their temp dirs in /tmp
Follow-on to #7337. Been seeing other CI test failures that point to
these temp directories, so let's just move all of them to /tmp. I'm sure
someone will write ext2fs stress tests later :^)

Example:

/usr/Tests/Shell/control-structure-as-command.sh
  Core::Socket: Failed to connect() to /tmp/portal/inspectables: ...
  + rm -rf shell-test 2>/dev/null
  + mkdir shell-test
  Error: The action has timed out.
