http-lib test failures when building dovecot-2.3.5 and later in mock builder

[Tuomo Soini]

There is random failure in test-http-payload when building rpm package
from 2.3.6. I couldn't reproduce that in normal system but that happens
something like every second try in mock chroot build envirnoment. Other
tests don't have issues so it looks like test is not very reliable.
Building 2.3.4 didn't yet have this issue.

./test-http-payload -D output attached.
