Add berrie64 to jenkins bot chain

[robe]

Bruce Rindahl provided us an additional Rasberry Pi which is 64-bit and will be called berrie64.

old berrie also had gotten upgraded I believe to 64-bit but is running 32-bit gcc I believe.

Anyway will setup berrie64 to do both PostGIS and geos tests. I'll put a separate ticket in for geos once I get to it.
