Update dead links

Abstract: this MR aims at updating dead links in the buildout.cfg files.

Context of the MR

Following MR !1430 (merged), which updated dead links for dependencies of the slapos package, I was left with two packages to update: pytracemalloc and kumo. Meanwhile, I also ran a script to find dead links in all software releases (not only slapos). Many dead links were found, which can be classified into:

• packages still used with dead links;
• unused packages.

This MR, linked to another one, covers the first category of packages, and updates the following software:

• apache-php;
• cups;
• geoip2 and;
• pytracemalloc.

No MD5 were updated, except for geoip2, which also gets "updated" (although it is not versioned as any other software).

Note about pytracemalloc

The pytracemalloc package has been switched from PyPI to manual building. This is due to the egg not being available using PyPI anymore: the name is now a security placeholder package, since the integration of pytracemalloc into standard library by PEP 454.

We still need this package since we use Python < 3.4 (actually Python 2), so I added a pytracemalloc part with download link to the old version.

Packages not updated

This MR is linked to another one which remove unused software, therefore all the packages removed were not updated in this PR, namely:

• busybox;
• corosync;
• embulk;
• jsl;
• lynx;
• mosh;
• nullmailer;
• pole;
• sheepstrike;
• zeromq.
