Log2Lines, ".iso" cache: support for duplicated files in reactos.cab is missing, like shell32.dll

Log2Lines cache uses 7-Zip to extract files from reactos/reactos.cab,
though that utility simply overwrites duplicated files (names) in .cab.

shell32.dll is the major example: second empty test file overwrites first 9 MiB O.S. file.

Then, such file addresses cannot be resolved.

• reactos-bootcdregtest-0.4.11-dev-40-g6d7ec8c-x86-gcc-lin-dbg.iso
