Fix test-suite under Fedora 40 modern C rules

Multiple tests are failing on Fedora 40 due to their distro-wide
C modernization effort, which cause our ancient "hello world" package
to fail due to implicit printf() function usage.

There are two separate issues here:
- hello-autopatch.spec had off-by-one in its patch application, causing
  the modernization patch to not apply (see rpm-software-management#3093 for the reason)
- others were using the original hello-1.0-1.src.rpm from 2007 with
  some very outdated practises, code and md5 hashes

Update the src.rpm, removing silly fubar while we're at it. Regenerated
now on x86_64 so adjust the test-expectation, and update the python archive
test to calculate sha256 instead. And, fix the autopatch test numbers.
