tdf#67538 XTypeDetection::queryTypeByDescriptor poor performance, part2

SfxMedium was creating a temporary file and copying the input file, when
CloseInStream_Impl was called from the destructor. Very very bad for
performance.

This is specifically fixing the performance of queryTypeByDescriptor
when called from a basic macro on a local test file.

This takes my test macro from 16.1s to 9s.
