MC: place .file records into the correct section

Browse Source 
.file records are supposed to have a section identifier of 65534
(IMAGE_SCN_DEBUG) rather than 0.  This is spelt out clearly within the PE/COFF
specification.  Fix this minor oversight with the implementation for support for
.file records.
