Bug#821457: gnutls28: FTBFS on amd64: killed after 150 minutes of inactivity during x509-auth.scm test

[Simon McVittie]

Source: gnutls28
Version: 3.4.11-3
Severity: serious
Justification: the obvious

gnutls is failing to build from source on amd64, again. I'm reporting this
as a separate bug rather than as part of #805863 because the symptoms are
different (but feel free to merge it if the root cause is the same).
Instead of a test crashing/aborting, we now see:

Build killed with signal TERM after 150 minutes of inactivity

I think this means x509-auth.scm ran for >= 150 minutes without completing?
