Release notes:

Upstream (pyuci developers) removed setup.py,
I bring it back to be able to compile it despite
that we do support building packages, which are
using pyproject.toml, but the thing here is
that their pyproject.toml requires setuptools 74.1.0
[1] [2], but Python 3.11 is using bundled setuptools
and pip [3] [4]. In current version 3.11.13,
there is still outdated version of setuptools, but
it looks like that in the newer version, there will be
new one [5].

Once, there is released Python 3.11.14 and updated
in OpenWrt, these patches can be dropped.
