HaikuDepot & PoorMan: Disable -Werror.

Unlike the last commit, I am not sure whether the memcpy/memsets
in here are properly safe to do. (They look OK, but a lot of them
involve template classes that probably should not make such
assumptions.)

But the code has worked so far, so let's disable the -Werror so
we can move forward with GCC 8 for now.
