[CORE] MapOutputTracker.deserializeMapStatuses: close input streams
GZIPInputStream allocates native memory that is not freed until close() or
when the finalizer runs. It is best to close() these streams explicitly.
@stephenh made the same change for serializeMapStatuses in commit b0d884f0.
This is the same change for deserialize.
(I ran the unit test suite! it seems to have passed. I did not make a JIRA
since this seems "trivial", and the guidelines suggest it is not required for
trivial changes)
