Fix #8127: py domain: Ellipsis in info-field-list causes nit-picky warning

On parsing the types, the leading dot of the ellipsis (...) is considered
as a reference name.  And its first dot is considered as a notation for
relative type reference (ex. ".ClassName"). As a result, it was converted
double dots unexpectedly.

This changes the parsing rule to treat the ellipsis as a symbol, not a
name.
