    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.
