calm not updating master x86_64/sha512.sum after setup updates

[Brian Inglis]

Hi folks,

After uploading packages, calm does not appear to be updating sha512.sum after 
updating setup.ini:

$ date -ud@`stat -c%Y ~/mirror/x86_64/sha512.sum`
2024 Jul 24 Wed 15:14:03

This is showing up in a script I run a minute or few later to check 
git/cygwin-packages/repo status, https://cygwin.com/pub/cygwin/x86_64/ 
timestamps, and download sha512.sum, setup.ini.sig, setup.xz.sig, setup.xz to 
check whether calm has updated every package as expected, checksums, and 
signatures, and it is okay to announce, using curl -I and a filter:
