Minor tweak to ComputedStyleBase.h.tmpl formatting

This patch changes the generated ComputedStyleBase.h code from:
    return true &&
        m_listStyleType == o.m_listStyleType &&
        m_textAlign == o.m_textAlign &&
        m_writingMode == o.m_writingMode &&
        m_direction == o.m_direction
    ;
to:
    return (
        m_listStyleType == o.m_listStyleType &&
        m_textAlign == o.m_textAlign &&
        m_writingMode == o.m_writingMode &&
        m_direction == o.m_direction
    );
