[master] Bumped up timeout values in D2 controller tests.

On the FreeBSD10 system installed on the physical machine with the CPU:
(Intel(R) Core(TM) i7-2700K CPU @ 3.50GHz), Kea compiled with clang 3.3,
it takes slightly more than 2100ms (the previous timeout value) for the
callback to occur. This seems to be specific to this system but on the
other hand we don't test on FreeBSDs a lot, so the problem may be more
common than we think. This was okayed on Jabber.
