[Rpm-maint] [rpm-software-management/rpm] RFE: Make `%setup` work with archives regardless of inner structure (Issue #2664)

[Matteo Croce]

I have a draft change in https://github.com/teknoraver/rpm/tree/libarchive2

Most of the work needed to be done in `rpmuncompress`, I added a `-p` flag which does the following:
```
$ tar vtf source-singleroot.tar.gz
drwxr-xr-x root/root         0 2024-01-16 19:13 source-xxxxxxxxxx/
-rw-r--r-- root/root        32 2024-01-16 19:13 source-xxxxxxxxxx/file1
-rw-r--r-- root/root     33886 2024-01-16 19:13 source-xxxxxxxxxx/file2
drwxr-xr-x root/root         0 2024-01-16 19:13 source-xxxxxxxxxx/dir1/
-r--r--r-- root/root       210 2024-01-16 19:13 source-xxxxxxxxxx/dir1/file3

$ tar vtf source-noroot.tar.gz
drwxr-xr-x root/root         0 2024-01-16 19:13 dir1/
-r--r--r-- root/root       210 2024-01-16 19:13 dir1/file3
-rw-r--r-- root/root        32 2024-01-16 19:13 file1
-rw-r--r-- root/root     33886 2024-01-16 19:13 file2
