    scripts: feeds: Don’t hardcode IS_TTY
    
    When building in environments that set IS_TTY, the feeds script does not
    honor it and passes a hardcoded value to scan.mk, causing unwanted
    control characters to appear in stdout.
    
    This commit addresses the issue by checking IS_TTY and MAKE_TERMOUT
    variables and uses their values if defined.
    
    Closes #8039
