stdlib: Do not check base64 input more than needed
Often the decode functions return a function_clause error, but not
always, and the errors have not been consistent between modifications
of the base64 module.
Now the errors are returned as they happen--no attempt to make them
look nice is done. The alternative, to ensure that, for example,
{badarg, Culprit} is always returned upon bad input, was deemed
pointless.
