Following advice from https://luajit.org/download.html use recent commit id,
but rely on github archive.

Dropped not applicable patch.

Also use directly archive with patches.

Changes:
 * use xz archive
 * stabilize patch name
 * update patch to current version

Expose pkgconfig configuration so that other parts can easily fetch it.

Drop fmhttp, as it's not needed to make http calls from our deployments, and
the updated version requires much more dependencies for this feature.

The fix for https://github.com/apache/trafficserver/issues/11784 is ready
for 9 branch in https://github.com/apache/trafficserver/pull/11835 , so use
the patch directly until new version is released.

We prefer to change the egg version at a different time (usually inside
a MR containing other changes).

e7369525 (stack/erp5: make haproxy reload script wait for old worker
processes, 2024-11-10) was an old version of the patch pushed
accidentally, this fixes the broken syntax

See merge request nexedi/slapos!1603

This is mostly to fix some flaky tests, because with the previous
approach of just sending a signal for haproxy to reload the config
asynchronously we don't know when haproxy has reloaded.

- update zope to 5.11.1
- update zodbtools to current master ( `0.0.0.dev9-21-gb0fdb5f` )
