fix memory leaks
Commit 5add23c7233c3f34fdfa6387873b1d3bdb93e1d6 and commit
2f4cdd4fd0580e3121773e89a7c6e7a9e1ffa54b introduced three memory leaks
which only appear in error cases:
* unzip.c leaks if a ZIP archive uses a compression method other than
store or Deflate
* xps-zip.c leaks if fz_open_archive_with_stream throws for broken
ZIP archives
* xps-zip.c leaks also if a piece of a split file is missing
