Commit e1d917182 added support for base64url encoding, a base64 variant
intended to be safe for usage in URLs and filenames. The padding rules
for base64url and base64 differ in that base64url require no extra '='
padding, but the commit unintentionally relaxed this requirement for
base64 as well. Fix by making sure that the truncation logic check
for the encoding and add a test to make sure.
Backpatch down to v19 where support for base64url was introduced.
