Closes: #66850

upx-devel: Update to 20230130

The commit hash was already changed in 2e54fc57 so some users who
installed "20211127" today might have actually received 20230130.

Disable -Werror, which the build enables by default if there is a .git
directory, because the build otherwise fails (at least with Xcode 12.4)
due to unknown warning flags being used.

This version requires C++17.

See: #66850
