GH-49638: [CI][Packaging][Python] Pin setuptools < 80 to build oldest
pandas to test on musllinux (#49639)
### Rationale for this change
Musl Linux wheels for Python 3.10 fail to install due to newer setuptools
not being able to build old pandas from source.
The version of Pandas does not have Musl Linux wheels and is the last one
to support the oldest numpy we support for Python 3.10.
### What changes are included in this PR?
Pin old setuptools in case of Python 3.10 in order to be able to install
old pandas from source. This will be deleted in a couple of releases once we
drop support for Python 3.10.
### Are these changes tested?
Yes via archery
### Are there any user-facing changes?
No
