In fcl-passrc, TPasElement.GetDeclaration does not display correctly type aliases declarations with basic types

The fix applied to solve the closed #issue 41135 has produced a regression in GetDeclarations, that arises with type alisases declaration with basic types.

For example, with the following program:

unit test;
{$Mode ObjFpc}{$H+}

interface

type
  TT=type integer;

implementation

end.

GetDeclaration function gives the following result:

TT = type
