New package naming broke dbdeployer.

Hi,

the new package names (Percona-Server-8.0.18-9-Linux.x86_64.ssl102.deb.tar.gz) breaks dbdeployer:

$ p="https://www.percona.com/downloads/Percona-Server-8.0"
$ l="Linux.x86_64.ssl102.deb.tar.gz"
$ p2="Percona-Server-8.0.18-9"
$ wget $p/$p2/binary/tarball/${p2}-$l
[...]
$ dbdeployer unpack -prefix=ps_ ${p2}${l}
validation for Percona-Server-8.0.18-9-Linux.x86_64.ssl102.deb.tar.gz failed: inner directory name different from tarball name
Expected: Percona-Server-8.0.18-9-Linux.x86_64.ssl102.deb - Found: Percona-Server-8.0.18-9-Linux.x86_64.ssl102

This could be considered a bug in dbdeployer, but it could also be argued that this is a package naming problem.

Many thanks for looking into that,
