bug#30841: Building Zend PHP (php): tests fail, and "Name or service not known"

[Adonay Felipe Nogueira <adfeno@hyperbola.info>]

This is known to started happening from a `guix pull' done in
2018-03-10T11:00:56-0300. I did another pull yesterday
(2018-03-16T16:30:42-0300) and the problem continued.

I didn't bisect this problem yet. That is: I don't know if it started
happening in a commit from dates before.

Here is perhaps the most interesting part of the log:

... I don't do anything, so I assume the build process is responsible
for "advancing".
