Subject: [PATCH] Fix false positive -Wstringop-truncation

Fix false positive stringop-truncation warning/error with GCC 10 on s390x by indicating GCC to explicitly ignore this case, as it is clearly a false positive (NUL is set in the following line).

This allow the compilation to succeed with -Werror on.

Fixes: https://github.com/swaywm/wlroots/issues/2018
