Fixes #102781.

With this change, running make regen-cases from an out-of-tree build (without any other source changes) results in an unchanged generated_cases.c.h (instead of resulting in changes to the filename of every #line directive).

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot s390x Fedora LTO 3.x has failed when building commit 174c4bf.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/55/builds/3132) and take a look at the build logs.
  4. Check if the failure is related to this commit (174c4bf) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

Note: switching to '174c4bfd0fee4622657a604af7a2e7d20a3f0dbc'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 174c4bfd0f gh-102781: fix cwd dependence in cases generator (#102782)
Switched to and reset branch 'main'
