[Decoder/Utils] Remove last empty label while enumerating labels from file

While parsing the labels file, a label per line is expected.
g_strsplit(file_contents, '\n', -1) is used to parse the file and
returns the label as a string vector.

The last '\n' in the file introduces an additional empty element, as the
delimiter involves 2 elements.

Hence, the patch is removing the last trailing '\n' to avoid this
additional dummy element in the labels list.
