lib: fix base64 encoding

Remove adding of line feeds when encondig. We're using these functions
only for encoding binary data for storing in YANG data tree.

According to RFC 7950, section 9.8.2:
```
9.8.2.  Lexical Representation

   Binary values are encoded with the base64 encoding scheme (see
   Section 4 in [RFC4648]).
```

According to mentioned RFC 4648, section 3.1:
```
   Implementations MUST NOT add line feeds to base-encoded data unless
   the specification referring to this document explicitly directs base
   encoders to add line feeds after a specific number of characters.
```

Therefore, line feeds must not be added to the encoded data.
