[regression] untargz fails extracting some folders

[franramirez688]

Changelog: Bugfix: untargz() method was failing if directories had a more restrictive mode.
Docs: omit
Closes: #17987

Now, it does not show the file percentage until we find a better solution for that:

Python 3.12.3 (works as expected)

conanfile.py (test/1.0): Downloading 142.8MB x-tools-x86_64-bionic-linux-gnu-gcc14.tar.xz
conanfile.py (test/1.0): Unzipping x-tools-x86_64-bionic-linux-gnu-gcc14.tar.xz to /tmp/tmp52l7sgb4

The key part is here (from tarfile.py):

class TarFile(object):
    # ....

    def extractall(self, path=".", members=None, *, numeric_owner=False,
                   filter=None):
        # ...
        for member in members:
            tarinfo = self._get_extract_tarinfo(member, filter_function, path)
            if tarinfo is None:
                continue
            if tarinfo.isdir():
                # For directories, delay setting attributes until later,
                # since permissions can interfere with extraction and
                # extracting contents can reset mtime.
                directories.append(tarinfo)
            self._extract_one(tarinfo, path, set_attrs=not tarinfo.isdir(),
                              numeric_owner=numeric_owner)

        # Do some stuff with directories

In a nutshell, it's not setting the attributes for those directories at that point, it's done later. It's not the same as it's done by the extract() method.

This test fails in the develop2 branch.
