[GENERIC viewer] Remove some, now unnecessary, checks used with fileInput

Browse source 
According to the MDN compatibility data, see below, all of these features have been supported for years and years in all browsers. Looking closely at the data, the most likely reason for adding these checks in the first place was for IE 9 compatibility (since we originally "supported" that browser).
