* base-files: Add shell test quoting

  tty can return "not a tt" which results in warnings when /etc/profile
  is executed.

* base-files: fix profile error under < /dev/null

  Previous attempts to constrain execution of `resize` to only TTYs did
  not properly handle situations when `tty` would return the string "not a
  tty". The symptom is "/etc/profile: line 34: test: too many arguments".
  Fix this by utilizing the exit code of `tty`. Also use `case` instead of
  `cut` to eliminate a subshell.
