    CMake: Guard script configure_file() calls with ENABLE_SCRIPTS

    The configure_file() calls for xzdiff, xzgrep, xzmore, and xzless
    were running unconditionally within the if(UNIX) block, even when
    ENABLE_SCRIPTS was OFF. This would cause a build failure if the
    src/scripts/*.in files were not present. Deleting those files can
    simplify license compliance when the scripts aren't needed.

    Move the foreach loop and related code inside if(ENABLE_SCRIPTS) guard
    so that configure_file() is only called when scripts are actually needed.
    This is mostly whitespace changes to adjust the indentation.
