mapi_abi: Get rid of unnecessary copy.

Previously, _get_api_entries() would make a deep copy of each element
in the entries table before modifying the 'hidden' and 'handcode'
attributes.  This was unnecessary, since the entries aren't used again
after this function.  Removing the copy simplifies the code, because
it is no longer necessary to adjust the alias pointers to point to the
copied entries.
