python3-pyasn1: Eliminated ptest deprecation warnings

Eliminated the ptest deprecation warnings for the error:
    DeprecationWarning: _int_ returned non-int (type SizedInteger).
    The ability to return an instance of a strict subclass of int is deprecated,
    and may be removed in a future version of Python.
       return SizedInteger(value).setBitLength(len(value))
