this is still hard-coding the "file has extensions that is automatically
removed by decompression command" assumption, which makes for a
difficult interface (what if we add a decompression command that doesn't
work like that? why is $dest now no longer the destination file path?)
switching to "decompress to stdout" like I suggested in the review of v1
would make the command returned by decompressor_info more flexible, as
it can then be included in a pipe (like we do for vma in
PVE::QemuServer::restore_vma_archive) or its output redirected to a
file.
then the whole decompression block can move a bit higher up, before the
rename, since $dest will remain the final destination path for both
uncompressed and compressed cases.

this is wrong - see the rather lengthy comment on top of run_command.
the string variant should basically only be used if you have a static
command, else use the array or array of arrays variant.
PVE::QemuServer::restore_vma_archive has an example, but it's likely
more complicated than you need here ;)
