[Rpm-maint] [rpm-software-management/rpm] Wrong version comparison (Issue #2574)

[Mattia Verga]

Trying to compare two package versions with snapshot information produces wrong comparison:
```
$ rpmdev-vercmp 1.7.0~202307168f43b0b 1.7.0~20230709062d5b2
1.7.0~202307168f43b0b < 1.7.0~20230709062d5b2
```
The first has `~20230716...` so it should evaluate higher than `~20230709`.

The version comparison seems to fail because the second hash digit is a letter and not a number:
```
$ rpmdev-vercmp 1.7.0~202307168 1.7.0~202307090
1.7.0~202307168 > 1.7.0~202307090

$ rpmdev-vercmp 1.7.0~202307168f 1.7.0~2023070906
1.7.0~202307168f < 1.7.0~2023070906

$ rpmdev-vercmp 1.7.0~202307168f 1.7.0~2023070906
1.7.0~2023071681 > 1.7.0~2023070906
```
