Subject: [PATCH 1/5] utils: Lower xz compression memory usage limit to 20%.

From: Maxim Cournoyer <[email-masked]>

There were sometimes out of memory errors on the Berlin build farm, especially
for i686 or arm machines having less memory.

* guix/build/utils.scm (%xz-parallel-args): Reduce --memlimit value from 50%
to 20%.
