AVRO-896. C: Snappy is an optional dependency
Buildbot doesn't have the snappy libraries installed, and it raised an error
trying to compile the C bindings with the previous
AVRO-896 patch applied.
Turns out we weren't being careful enough when the Snappy library (and
presumably the other compression libraries) weren't installed. Now this
correctly results in a good build, of a library with snappy support turned off,
